70 % of the people can taste PTC
30 % can't
30% = 0.3

t = square root of 0.3
T = 1 - square root of 0.3

Why is exercise important?

Well, everybody knows it, exercise=health, try to work out -- it's good for our health.

Yesterday, my friend asked me: why is exercise important? and all i could think of was turning fat to calories and losing weight. :|
But actually why is exercise important from the biological point of view?

The gene expression will be different, I think, environment affects the phenotype of organisms but I don't think that it changes the DNA or what.
