The body responds to pain and stress with a rush of endorphins (same as "runner's high"). Some people's response is higher than others and they enjoy it. We generally call those people masochists.
I disagree....I think it just has more to do with run of the mill actors these days more willing to go on anabolics to get ready for film roles. Its no secret guys like the Rock, Mark Wahlberg, Chris Hemsworth, Hugh Jackman etc etc etc all dabble in PEDs to get ready for such roles. You can find examples of big dudes in shows from yesteryear if you look for them. Hell, I'd argue that Steeve Reeves there from the late 50's was in far better condition than your typical "action hero" from the current year.
Those five or six guys are literally like the ONLY big guys in film back then! And most of them aren't actors, they're bodybuilders cast solely for their physique (and they were juiced to the gills too). Now EVERY actor is bulked up. Even Ben Stiller juiced for Tropic Thunder
I've sat for 8 hours. Your body responds to the pain with adrenaline and it gives you a buzz after a while. I was heavy into that scene of tattoo shops and body mods for a while mainly because a good friend owned a few shops. Folks who are into ink and body mods share that experience of the pain high. The people who do suspension especially say it's an incredible high. Suspension has been around in various cultures for hundreds of years and is still practiced. Same with piercing. Folks on the outside tend to think it's all about appearance and some of it is but a lot of it is the high and pushing personal limits with each other.
I get just as much shit for being a size 2 as people get for being a size 22 - Some one else's body is none of anyone's business - I don't know why it matters if someone want's to look like Jabba the Hutt or a matchstick. If the reason for being pissed off about fat people is a mate, however, That's just too bad. No one is entitled to one of those. If you don't like fat people, and there are no un-fat people available to you - that's the way the cookie crumbles. You are not owed a skinny hot thing, just because you want one. That is a huge problem with the exposed incel/"nice guy" crowd currently - they think they are owed the mate of their choice and flip out when they are turned down.
The one I got on my hip hurt and it's the size of a quarter. It took me a long time to get back into that seat - it was well worth it though. I was high as fuck by the time I got done Having a baby without pain meds, did not give me the same results. 0/10, would not recommend. Same reason I run into burning buildings and ride a motorcycle though I guess - The Adrenalin dump is addicting.
I think those dudes were brothers or something, maybe twins? Yeah: http://www.entertainment-geekly.com/web/general/jan2005/robbloom
We are not fat. We just have big bones... When I was in 40 minute moto shape I was about 165 lbs. I am currently right around 180. I know that I had more muscle mass back then too. There are exceptions to the rule but most of the weight gain is fat...
Your body responds to pain - especially pain that is ramping up and/or relatively constant and can't be stopped by movement - by releasing the brain's own opioids, called endorphins. The initial adrenaline release (which prepares the body to fight or run) is commonly followed by the release of endorphins, which increase pain tolerance by essentially the same paths as opioid drugs. Many BDSM players play specifically to achieve the organic high from the endorphins. Its also very, very common to achieve endorphin release while enduring the tattooing process.
