I live in one of the largest and most bike aware places. It is still just a numbers game and luck. It certainly will cut my life short as is and disability sucks, but I still ride. No one can predict someone pulling directly into a passing car from a parallel parking spot. That level of stupid is beyond belief, but it does exist, and it got me riding to work 2/26/14

Same, in my case it would probably be detrimental to my health, since I’d have to ride down stairs to get to my office.

Get a home trainer then you can ride from home

Not to mention the saved fuel cost, car maintenance cost and/or public transport cost ( though the latter is often reimbursed by the employer as well ).

You do get some money for driving to work in your taxes IIRC, but not even close to what you spend.

For lifting weights it’s confirmed that your prolong your life by more than what you spend in the gym, i think for 30-45 min sessions, which is enough.
