I average between 8 and 10k steps a day, so 2000-2500$ a day vs 36*24 ~= 864$
Someone pointed out you could loose your ability to walk in an accident or due to old age but you'd be breathing until the end, but at 3x the income you could easily invest and save to end up much wealthier than you would with the slower but more reliable breathing option
But regardless of which option you choose you'll be set for life, but it'll still probably take you hundreds of thousands of lifetimes to get even a fraction of Jeff Bezos wealth
I think I'd go for the steps just so I could build a nest egg faster and that generates passive income that way. 10000 steps in a day isn't too tough (especially if you don't need to work anymore) and that's $2500 which is about triple the breathing amount for one day. Hell, I do over 20k steps some days. Even if I only get steps in on weekdays I'd still easily double the breathing income and getting more money earlier makes all the difference.
Plus I'd be getting paid super well just to stay somewhat active which is a win-win.
Ok, so average respiration rate for adults over 18 during sleep peaks at 20 breaths per minute. That's 1200 breaths per hour, and with a cushy 8 hours of sleep, that's a whopping 9600 breaths while asleep, maximizing the average. That would net you $480 just for sleeping.
In comparison, on average at a 3 miles per hour pace, it takes 20 minutes to walk 2,252 steps. $480 would take 1,920 steps, and would take about 15.5 minutes to walk at the same pace.
So, 15 minutes of relaxed but purposeful walking would match the total amount you'd make on average for sleeping.
