Great responses, everyone. The fact is I'm in my 40s, smoked for 20 years of my life, am about 30 lbs. overweight, and I know I have more stamina irl than my character. Fortunately, mods fixed this issue (and a ton more, much like Skryrim for example).

Personally, I'm just trying to enjoy the game before it grows bigger and the devs are forced into "diversity & inclusion" wokeness.
