You're lucky if this is going to be less than 2.5 hours each way.
I live 38 miles north of the city; Poughkeepsie is 73.5. It takes me about an hour and 45 minutes door-to-door to get to work at 22nd street. 10-15 minutes to the train station, probably about 5 minutes of waiting [because if you miss one train, you have to wait 20-30 minutes or so for another depending on the time of morning], 60 minutes on the train, then about another 25 minutes of walking (or alternatively 5 minutes to get to the subway, 2-5 minutes to wait for it, then 5 minutes on the subway, and another 5 minutes of walking).
- pets like dogs/cats always tend to raise happiness levels - daily long commutes to work tend to make people more unhappy (and of course it helps if you have the time for yourself and are nto constantly stuck at traffic jam)
At least the trains have internet (or at least Amtrak does). If you can spin "they have wifi so they'll be part of my work day" into your job and work a virtually eight hour day including the commute as part of your time, that could be doable. If you have to commute on top of a normal eight hours, that's a non-starter.
