The little daily things add up, not doing exercise can significantly impact not only your weight / insulin levels, exercise is to release endorphins for the day to help make better decisions and live a happier life. Daily routines of the .05x stack up. That's the point. 1% better a day in any given area of life is still better than 0. Who cares about the 10x, why is that even a factor? Just be a good human and contribute the most you can, when you can.
