How to make everyone healthy

Or there'd be a new job. Cell Phone Charger! The people who like to work out would then get paid for doing something that they enjoy, and the people who don't want to work out would just have to have enough money to buy a charge.

That's fairly similar to what I said. If you have the money to pay someone to charge your phone for you then it makes it easier on you and in turn you become lazier and in more reliance on someone else charging it for you.

I would definitely work on a treadmill to charge phones and earn money. I get profit and so do random people.
