I've been into fitness since as far back as I can remember, in one form or another. One thing has always stood out like that neon billboard in Times Square to me:
People will do the stupidest, most unhealthiest and dangerous things in the name of fitness and health. "Gym 'tards" at best are comical and at worst annoying and/or dangerous to themselves and everyone around them. I can't say I actually ever measured up to the "gym tard" level, but I have definitely done both unhealthy and seriously dangerous stuff. I would definitely include lifting and drinking in the latter.
The weight training until the past couple of years was always secondary to functional strength and endurance to me. I practiced martial arts, played basketball, kickboxed, rock-climbed, swam, ran, and just about anything that presented a physical challenge, not to mention all the Marine Corps crap I had to do The entire time I was on active duty. When I retired and decided to be an electrician, I was always hanging off crap, climbing ladders all day, humping conduit and other materiel, so I was getting my functional exercise.
My functional exercise now consists of chasing a soon-to-be 2 years old all day and if you don't think that'll do it for ya, give it a shot
I have always been of the opinion that muscle that doesn't work isn't worth much. Kinda like having a 350 under the hood and a a transmission from an AMC Pacer. If you can't get that power to the ground it's just a lot of noise.
