I like these kinds of visualised talks, and although this doesn't tell you anything radically new it is still worth watching (unless you don't like illustrated talks!).
We all know that exercise is good for us but sometimes the message is confusing. Hopefully this talk will encourage you to make moving a part of your day. With all the recent talk about how much exercise is good for you and whether running long distances is ultimately damaging, this talk gives a research perspective on the value of exercise for positive health outcomes. The debate will still rage about over-exercise but the value of moderate exercise cannot be understated.
What is fascinating is some of the research cited. Another interesting thought is the "Whole Body" impact idea that comes up when he talks about stents. Think about the implications for a while. If a stent only fixes one part of the problem, but exercise addresses a wide range of factors, ho might that be true for other diseases/ risk factors?
