Not so simple:
If everyone will be driven door to door with little walking and little cycling, we’ll end up with more obese cripples with bad knees at age 55, not healthier people. Policy should exist to encourage exercise and human mobility as part of urban design — it’s a lot easier to exercise when you have no choice vs going to the gym and running like a hamster on a bloody wheel.
Policy should be towards better health care and urban design so that most people don’t have to live as long as cripples before they kick the bucket. People usually don’t end up crippled when they’re old if they’ve made good choices.
Blindness often comes from diabetes (due to inactivity), so do things like kidney and walking impairment. Which is a nice way to say losing limbs.
