Not to mention that all the additional biking will improve people's health, thereby reducing the costs (and emissions) of healthcare and medication.

Last I heard, the jury was still out on costs of obesity care vs old age care. Anyone have an update?

There's an argument to be made that people who are healthier throughout their lives will be able to have a higher quality of life, and need less care, well into old age. So even if they live longer it might not cost as much in old age care. But you're right that that's more of a gut-feeling/heuristic kind of thing. We'd need actual numbers to know for sure.
