Very nice!
Playing chess early in the day, may be healthier.

Oh God, not another damn study!...

"If there's a way to manipulate the human diet to let us live longer, we haven't figured it out yet and it may not exist," said biologist Steven Austad of the University of Texas Health Science Center's Barshop Institute for Longevity and Aging Studies

There is no need to be overly concerned about increasing the human lifespan. The problem will self-correct, eventually. Forget about blood sugar, stem cells, melatonin, Sara Tonin, or whatever. In the evolution of biological entities, continued exposure to various hazards produces a refinement of the gene pool, resulting in immunity. Millions died of the Bubonic plague in the middle ages, but the few who's immune systems resisted the microbe, passed their genes on to subsequent generations, who of course were also immune. After enough people die of any particular malady, an immunity is developed and the problem is eradicated. So it logically follows that, after enough human beings die of anything, they will eventually develope an immunity to death.
Too many variables make this an uncertainty

I haven't the time to read the study, but I assume it proves the obvious benefits of drinking in the morning.
Otherwise it might just be an annoying vegan roomie.
That's the reason I call em vedges.

Thanks for your comments. Nimzoroy. Steve Austad is a friend. I will have to ask him why he ignores many excellent studies including those looking at Okinawans by Dr. Brad Wilcox. Dr. Wilcox and colleagues showed that by limiting calories by only 11%, they have the longest lifespan in Japan probably the world.
Here’s the citation and the blog where I discuss it more.

I brought the topic up here though, because of the possibility of using a CR Way of life to increase chess capabilities.
Sometime in early 2013, we will launch a global longevity study which will look at many things including cognition. I would like to include a cohort of chess players who are really serious about their game. My contention is that, other things being equal, a chess player who controls calories and glucose will maintain or increase their rating over time, just because of the increased neurogenesis and other cognitive and stamina benefits of the lifestyle.
Here’s more about it:

[COMMENT DELETED]
Today I played a 90/30 chess game with a new friend who graciously accepted my offer of 10:00 AM for starting the game. At the end of our game, I thanked my opponent for starting the game at the “healthful” time of 10:00 AM (ET), saying that it is better for blood glucose. That provoked him to ask me to explain. So I thought others might benefit if I answer him by posting on this forum.
Before I explain why this is relevant to chess, you need to know a little bit about how the body ages and how you can affect it.
Studies show that the rate at which our cells divide (in most tissues) affects rate of aging, disease, and mortality risk. Besides standard cell division, we have only a finite number of stem cells that produce other cells that will divide and repair your tissues. The more calories and /or blood sugar that your cells get, the faster they divide and the faster you use up your stem cells. When those are used up, you are a goner. It is like withdrawing funds from a savings account. If you withdraw money too fast it gets used up and you are broke.
The good news: You can slow the rate at which your cells divide by giving them less energy – less total calories and, thus, blood sugar. (For those interested, here’s a more sophisticated explanation about how this all works in a presentation that was filmed for UCTV. http://www.uctv.tv/shows/Food-and-Addiction-The-Other-Side-Chronic-Calorie-Restriction-for-Healthy-Living-18566)
Now, back to chess: When a person plays a long, intense game of chess, it is very likely that the fight or flight hormone, adrenaline (otherwise known as epinephrine), gets revved up, which among other things sends your glucose soaring. That’s not healthy if you leave it that way. High glucose not only accelerates aging, but increases risk of major diseases – Alzheimer’s, diabetes, cancer, etc. It also hastens memory decline, so if you want to play good chess for a long time, listen up!
If, however, you play chess early in the day, like starting at 10AM, there’s plenty of time afterward to take a nice long, vigorous 45-minute walk, which should lower your glucose level nicely. If you play chess late in the day, there’s little you can do to lower your glucose levels: Vigorous exercise at night will negate your body’s secretion of melatonin, starting another cascade of health problems.
The flip side: benefits of glucose control are extraordinary. You will very likely live longer and your chess game will improve as your brain cells become more energy-efficient.
I have greatly simplified this. For those who want to read more about glucose control, check these out:

I wish all happy, healthful chess.
