It is a grim irony we humans over the eons have understandably desired:
1. easy work
2. plentiful and tastey food
Now that we have these things we find out that it kills us!
Who could have known?
Heart disease and diabetes and a billion other diseases are killing
us because we don't exercise and we eat too much. These were
problems available only to the rich in the past, but now with our
general affluence dieing is more equal opportunity.
If you think about it, it is possible to get no meaningful exercise.
At all. None. Zip. You have to go out of your way to exercise.
