Physical Activity - Why, When, Where, How Long, Which ?

Over the last year and a half, through a dozen odd articles, I have written how physical activity (PA) is the single most important factor in our quest to live long, healthy. In fact, PA can even overcome the downsides of poor sleep. Last week, I wrote that even if we do not have robust data regarding the health benefits of yoga, just as a form of PA (yoga as exercise), it should by extrapolation, increase our healthspan and lifespan.

While, walking is the simplest PA and any activity is better than none, there are still many questions about PA that need to be answered. Which type of PA is the best? Do I need to be active all through life? Does it matter when and where I am active?

A clutch of recent articles has tried to answer these questions.
