...but the bodies of 60-year-old chain smokers.

That's not really saying a lot.

Working out is fine, but excessive sitting in a chair is unhealthy in and of itself.

If I understand the sitting is dangerous research correctly. It says that it doesn't matter if how much or regularly you exercise, if you regularly sit for a certain amount of time it's still a health risk.

That's something I hope will change in future generations. Because I don't think we'll ever think it's a good idea to move around while focusing on doing something creative on any sort of canvas. We will always end up walking into things and our big toes will always find the sharp corners. Also, working while on a treadmill is just silly.

Therefore we must change our genes so that humans get a body that can sit for hours regularly without health risks.

So what if we are out of shape? Put a couple of guns on a drone and we'll match wits with the best in the world and live to tell the tale.

Barbequeing is a hot sport!

Do you smoke? or have asthma? I have light asthma. It can make it harder to get the exercise I need, even if it is only light asthma.

They are good if you want to scare away the women. They all want fat, balding men. (Just watch any good sitcom for evidence.)

Nah, muscles will un-tone in no time, and you can bulk up on fat really quickly. Just eat a lot of junk and don't exercise. It'll kill your muscles AND gain lots of fat. 2-for-1.

I've heard that some actors have gained 40lbs or more in a few weeks for a part.

No. At least, not regularly. I smoke "socially" when a situation calls for it (which is rare, though I'm still not proud of it). I'll also smoke Captain Black cigars when I'm trippin' and actual high quality Cuban cigars taste pretty decent so I'll get one now than then (like once very couple of years).

When I was a child I was diagnosed with [mild] asthma by "my" family doctor. He gave me two "puffers" for it. They never actually seemed to help though and I eventually stopped using them a long time ago. I haven't died yet. It makes me think that I was misdiagnosed. Whether for profit or incompetency, I don't know. Maybe it's just mild enough to not kill me, but again the puffers never seemed to make a difference. During the testing it felt "wrong" to me. I'm not a doctor so I could easily be wrong.

I love to shoot hoops and used to do it for hours a night. It's more enjoyable on your own^[1] and with music because you can "meditate". It would get hard for me to breathe, to the point where I would cough up shit, but that never stopped me. That isn't really my problem (though I was always more of a shooter than a runner).

Personally, I'm too insecure and anxious to exercise in public which "eliminates" things like walking (which BTW isn't exercise), running, or bicycling on the streets, or joining a gym. That's predominantly why I don't get much exercise. The property that I live on is in the middle of wet lands so it gets really messed up every spring and doesn't dry until about August which only lasts until September. I spent a lot of months playing in the muck and getting covered in wet clay during elementary and secondary ("high") school, but these days I'm not motivated enough for that.

Those actors are "prescribed" with diets and lifestyles specifically designed to gain weight quickly (without threatening their life) for roles that they deem worth the risk. They're practically eating butter 8 times a day.

It's not hard to keep weight off when you're fit. In fact, it practically happens automatically as long as you don't eat as a vice. Indeed, it's relatively effortless to keep weight fat off when you're fit, and keeping muscle should also come pretty naturally.

Yeah, fat gain/loss can happen very quickly. It's muscle gain that takes many years. It's where all these "I got ripped in 4 weeks" adverts come from: invariably it is someone who has spent years bodybuilding and has then completed a 4-week cutting phase. It only works if you've got enough muscle not to look emaciated after the weight loss. The final cutting phase is about 0.5% of the total effort.

What makes me laugh is when gym newbies say "I don't do weights because I don't want to become too big". Even if you eat the perfect diet and follow a perfect weight-training routine for an entire year, you won't naturally gain more than 1 -1.5 kg of muscle.

You were growing.

Regardless of your gains in height, that was an adolescent growth spurt that was probably slightly augmented by your training. What really matters while you are growing is genetics and protein consumption.

I'm talking about the gain of lean muscle mass in adults.
