Assuming I'm an average driver, and across a 30-year career, that commute is increasing my changes of dying something like 0.3%, given the number of miles I'm driving (that's a whole lot higher than I expected!) by car vs. 0.03% by bus. But...by bus, I've spent an additional 3% of my entire life (assuming I live 100 years = 876,000 hours) commuting, so the balance of that equation shifts pretty far in favor of car commuting (and I'll switch to electric at some point soon once EVs are purchasable without a 6-12 month wait...).
I will grant you that riding a bike 4 hours per day would probably improve my lifespan more than that 4 hours (due to improved fitness), though will likely also cost me my relationship because all I'll be doing is working and commuting to work. But this would enable me to move closer to work! Win/win!
Yes. You're replying to the meme comment: "We tried nothing and we're all out of ideas." and you're literally saying you're out of ideas.
>by doing what, exactly?
You've already mentioned you have a 30 minute commute. What could you do to reduce that? Maybe your SO has better options for public transportation to their work than you do and you could move to take advantage of that while giving you a commute close enough to bike. You could car pool. You could work with your local government to increase public transit options. Get an E-bike and take that to the faster public transportation routes instead of waiting 2 hours on the bus. You could just take the bus.
There's a 20 mile differential between my SO's work and mine. And this is one of the closer options work-wise for me. So...either we both commute by car or I do.
My bus option is a single transfer. But it still takes 2 hours. Bike to the transfer takes the same amount of time as taking the bus. E-bike 20 miles is a possibility, though we're probably talking higher chances of death that way than a car. Biking by human power would probably be lower chance of death (due to lower speed and better cardiovascular health).
Working with the local government generally doesn't work...especially for something like this where it's adding a bus route for one (which is worse than a single occupant vehicle). I'm like the definition of a case where single occupant EVs make sense...
It's hard to change you life to avoid such a convenience, but it's possible if you try.
