Exercise and Brain

Recently I attended a talk presented by Dr. John Ratey , a professor of psychiatry at Harvard Medical School.

The presentation, content and the afterthoughts were so compelling that I cannot resist sharing this information and enlist your serious feedback.

First, the topic: “STRONGER, FASTER, SMARTER, The Amazing Science of Exercise and the Brain”.

Second, the speaker: Dr. John Ratey is a professor of psychiatry at Harvard Medical School. In his entitled, Spark: The Revolutionary New Science of Exercise and the Brain, John Ratey presents new scientific evidence that exercise should be viewed as a medicine and that without appropriate levels of activity, our brains actually “shrivel.”

Last but not the least are my thoughts or the key take aways from the discussion.
Again, I paraphrase these in my simpleton terms. Scholars can pick up the book and dissect the medical terms, but here are the seven things which I learnt.

1. We are basically Hunter/Gatherers
Human beings are essentially hunter, gatherers. Just a few years back (around 10000 or so) we had to run 8-10 miles each and every day to get food. You did not move, you get did not get to eat. Only recently, particularly in the last 20 years or so we have created a society of gadgets and gizmos, of mashups and widgets where even my family of 4 are instant messaging each other to move from one room to another to get together for FOOD! (not true)We have created a social affliction called “sedentism” which has limited our physical movement and hence exploded our collective obesity. According to Dr. Ratey as many as 10 diseases, from blood sugar to blood pressure can be linked to obesity and sedentary lifestyle. Believe it or not, 20% (I mean 1 in 5) kids entering kindergarten are obese! Sigh!

2. Evolution of the brain

Over the years of human evolution, the back w8 so we have 2? say stuff clearly brain (the input source) has remained the same. It is the front portion which has gone through serious change which sets us apart from our ancestors. Most interesting amongst this is the “executive” portion of the front brain. The part which is responsible for organization, planning, learning from mistakes etc. Dr. ratey contends that the development of this executive portion is accelerated by exercise. Daily vigorous exercise. He gave charts and plots, examples and studies to prove this.Exercise is the “Miracle Grow” for the brain!

3. Exercise and Mental Acumen

Contrary to stereotype (I am speaking for myself), exercise does not make you a dunderhead. It sharpens your mental skills, your analytical abilities and processing power.“All things being equal, a physically active student has an advantage in learning; an inactive student is at a disadvantage for learning. Research even suggests that physical activity can impact student performance enough to elevate test scores”

4. Exercise and Depression
This I knew. Every time I exercise, I feel a high! Running is almost like a low grade drug for me. However, studies after studies have shown that you keep a group of patients in anti-depressants and a control group under exercise and the second beats the first. Also another trick which psyches use is to get an agitated patient for a walk. If they are still agitated you take them for another walk!Good to get a scientific validation!

5. Exercise and Education
Now this is interesting! Apparently kids who are exercising are not only making better grades (compared to when they were not), they are demonstrating more acumen and having much less behavioral issues. Data from schools after schools were presented to this effect. Most interesting is the Naperville School District which has made a serious commitment to FITNESS over last 20 years. The jaw dropping statistic was, overall US ranked 11th and 12th in math and Science when taking tests against other nations (Japan, Korea, Singapore are usually at the top). However, Naperville Central took the test as a country and came as #1 and #6.WOW!

6. Exercise and “NEW PE”

There is a difference between “sports” and “fitness”. Now this gets very close to my heart!Throughout our childhood, the “PE” class was a period of shame and agony for people like me. I was overweight, clumsy and lacked any skills in any sports whatsoever! I still have not gone far. However, the new PE is not about whether you are the fastest bowler, or the most daunting defender in football or someone who can hit aces after aces! PE is more of a competition with ones own self. Whether it is walking, running, swimming, biking, hiking, climbing, dancing or karate, just pick one and keep doing. Do it more, do it better and enjoy it to make it a part of your life.Just keep moving!

7. Conclusions
For me, it was a “milestone” lecture. I plan to study this, practice this and promote this.I thought I would share this with you, so that you exercise, you ask someone else to do the same. Whether it is a child, friend and even parent (oh yes, exercise is for ALL ages) request someone to do the same!

Twitter, few weeks of serious usage

It is addictive, it is educational and yes, it is quite different!
The overall momentum around Twitter and the related ecosystem seems to be exploding. There is a tidal wave of information in the internet. I will not even attempt to replicate it.

In my last Twitter post, I raised a few questions regarding how to use Twitter and its related features. Here, I will try to answer some of those and quickly share my experience.

1. Regarding ReTweets, I found TweetMeme and its ReTweet Button to be quite useful. It was simple and straightforward and it works. I could even add a button to my blog!

2. Over last few weeks, I have started following (and be followed) a few heavy weights. Tim O'Reilly and Mashable are a few to mention. It was truly eye opening! It was like having your ear to the ground of what is happening right now in the universe(at least in our planet) and also getting an expert commentary. Very nice! I have even started following President Obama, although he has not reached out to me. At least not yet!

3. To track trends, I found TweetStats simple and helpful. There are a slew of tools with all kinds of sophisticated features, but this one had enough for me to digest.

4. For those who have not figured out hashtags, I will request them to try out hashtags . As we learn how to research on our favorite topics using the tags, we will understand the difference between Google Search and Twitter Search. Someone truly pointed out that Twitter is a thoughtstream!

5. I am yet to discover the value and difference of direct messages.

6. I loaded up my desktop with Twirhl and TweetDeck. Both are powerful and rich applications based on Adobe AIR. But I still remain a loyal plain vanilla web client user. I have loaded my iPhone with TwitterFon.

Overall, I remain fascinated by Twitter and the eco-system. The level of enthusiasm (related products, tools and news) seem to be ever expanding. On the business front, two things are worth mentioning:

A. Dell Outlet passed $2M in sales using Twiiter channel: http://mashable.com/2009/06/11/delloutlet-two-million/

B. Comcast seems be using Twitter for customer support. Try #comcastcares and check for yourself.

At least for now, my Twitter expedition is on. I will come back and report more in two more weeks. Stay Tuned!

Twitter, What I learnt recently!

I am a late adopter. Noticed it since inception, but it seemed silly to me to pay attention. Oops!
Fast forward to November 2008, almost everyone I know is in Twitter. I decided to setup an account, log in and post a few tweets and accumulate a few followers. Kind of a slow start. Fast forward 6 months, May 30, 2009, Time publishes this seminal article (IMHO) regarding Twitter:

Here is my digest:
A. Twitter has an estimated 32 Million users growing at 50-100% a month. Wow!

B. From Britney Spears to Lance ArmStrong, all celebs are on Twitter. Who am I to resist?

C. Time predicts that it will have a *profound* influence on our life and businesses. From brand marketing, conducting surveys, micropayments, media and government alerts to local businesses Twitter may become the platform to play on. Hmm!

If you want to read the whole thing check it out the Time article.


Now, I am techie type. At least, that is what I think of myself! So hunting around for where I can learn more, I found a Youtube Video by none other than Mr. Tim O’Reilly. Mr. Web 2.0 himself! He has recently co-authored a book on Tips and Tricks of Twitter. I would provide my summary as a list of key questions to you.

Assuming you already have a Twitter account and have done some tweets and friends, do you know?
  1. How to ReTweet?
  2. How to Search for People, Words, Places and yes Attitudes?
  3. How to Track Trends?
  4. What is a hashtag? E.g. #wave
  5. How to send a direct message using @
  6. Do you have desktop tool like Twhirl?
  7. Have you setup a way to track links using a service like http://bit.ly/
  8. Are you familiar with interesting services like stocktwits or twitpay?
  9. How some large businesses are using or thinking of using Twitter?
  10. How the entire ecosystem might evolve?

I guess unlike me you are already up to speed. Just in case you are not, you might want to check out the YouTube video

Rich Social Web

I attended Web 2.0 2009 here in San Francisco today.
Needless to say, it was a low key event compared to 2008. Total attendance, level of crowd, number of exhibitors and announcements all appeared subdued. Since I went all the way to the city, I put on a brave face and started covering the show.

I am sure there several other trends. However, one thing which I picked up was Web 2.0 and Social Networks are embracing Rich Internet Applications (RIAs). This was apparent from two things.

Firstly, Adobe and FaceBook announced a Partnership. Adobe ActionScript 3 API has been made available for FaceBook. This will allow developers to deliver Rich social applications on the web using the Adobe Flash/Flex Platform. I attended the Adobe booth and indeed this was one of the key highlights with a FaceBook engineer showing off a Flex based game on Facebook. Looked really sleek! This was indeed interesting when I recalled that not too long ago (2007) Microsoft had bought a small piece of Facebook for $240M!

Well, wondering what the giant from Redmond was up to I went over to the Microsoft booth. No surprises, they were showing Windows 7, IE8, Azure and last but not the least SilverLight and ExpressionBlend. When asked about the Adobe and Facebook partnership, the presenter at the booth invited me to a joint session with MySpace later in the day.

I showed up for that session to learn that Microsoft has made a partnership with MySpace and developers can now use Silverlight to build rich media features into OpenSocial applications. The session had evangelists from both MySpace and Microsoft and they showed off the MySpace SilverLight SDK. The show was well attended and received. The key application shown was game to teach children on recycling and environment. Use of Expression Blend to develop RIA effects was very impressive!


Considering these two strong partnerships, I believe we will see a whole set of richer social applications in the near future.

Green & Clean Tech

This week (Feb 5th, 2009) I attended the Green&Clean show here in Menlo Park arranged by SD Forum. The overview of the event can be found in here.

First things First:
It was attended by over 100 people and had 6 panelists moderated by Greg Heibel from Orrick. The session continued from 6- 9 p.m. with some mingling at the beginning and tail end and was attended by an inspired audience. To me (someone totally green about green) it was a session worthwhile attending.

My biggest takeway was a high level on Obama/Biden Energy Plan. Here it is:

• Create five million new jobs by investing $150 billion over the next ten years.
• Within 10 years save more oil than we import from the Middle East and Venezuela.
One million Plug-In Hybrid cars – up to 150 mpg – on the road by 2015
• Ensure 10% of electricity from renewable sources by 2012, and 25% by 2025
• Implement cap‐and‐trade program to reduce greenhouse gas emissions 80% by 2050

You can read the full details here.

Ten Additional Things which I learned:
1. 2008 saw huge VC funding in Green & Clean. That money is still in the hands of startups!

2. City of San Jose has a huge green initiative. You can access it here.

3. California is uniquely positioned for Green & Clean because of Mojave desert and great Sun!

4. California uses 50% per person electrical power compared to national average.

5. Trying to explore Social Network & community technologies, I found about Positive Energy.

6. Researching about this show i found about this tool to track Clean Energy investments

7. Here is the link to Kleiner Perkins Green Initiative:

8. AB32 is a big deal.
AB 32 Bill requires that by 2020 the state's greenhouse gas emissions be reduced to 1990 levels, a roughly 25% reduction under business as usual estimates. The California Air Resources Board, under the California Environmental Protection Agency, is to prepare plans to achieve the objectives stated in the Act. Green House Gases include CO2, CH4, N2O, HFCs, PFCs and SF6 in the Kyoto Protocol.

9. This field needs Interactive Reporting.

10. Green Tech must make sense, watch Vinod Khosla.


I will eagerly await your thoughts.
