Even when he works out, he is probably working indirectly, like perhaps he has aides with him, doing, scheduling or what have you.

It's unfair to compare the average Joe to the POTUS. The POTUS has an army of aides to help him in his duties and he is expected to maintain good health.

A better way to approach the problem is to help people identify where there is a waste of time happening and guiding them to reduce that.

Personally I feel that smartphones have robbed us of our free time. They have seriously reduced our attention spans, have been feeding us endless information, most of which is useless and have made us borderline addicts. To maintain a healthier lifestyle and find more time per day, I would seriously consider ditching the smartphone and make do with a feature phone.
