Reply to comment by aus_ben93 in eli5 - If our cells only turn a certain amount of times before we die. Does causing micro damage from resistance training shorten our lifespan? by aus_ben93
I do my best! Just make sure you're not tinkering too much with your molecules, and you should be fine. Things like smoking, drinking, unnecessary hormones or supplements beyond reasonable amounts (ask your doctor if you're unsure), chronic inflammation and poor diet can really do a number on a molecular level - so drink water, eat fresh balanced nutrition from varied sources, get plenty of fiber (you wanna keep your gut flora happy if you want everything else to be happy!) and stay low on inflammation-inducing foods, and your DNA will thank you.
Oh, side note! Pay attention to your stress levels. I'm not talking physical workout stress, I mean brain and trauma type stress. High chronic levels of cortisol can really do a number on your telomeres!

That's at rest. If they are active, say walking around in an airport while carrying luggage, that goes way up.

when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air.

That’s true, but those guys tend to build unnatural amounts of muscle through anabolic steroids and hormone treatments like TRT. This puts more muscle on the frame than the body is designed for, and combined with heavy training leads to faster aging and often heart conditions or other cardio-vascular issues. For the average person who is simply muscular and strong in a natural way, these are not relevant people to look at.

Yeah I get it now. It’s basically just survival of the fittest (or sweetest)?

That could well be; I don't know. But you see the same kinds of design in any large indoor space designed for a lot of people, not just in transportation terminals: shopping malls, ballrooms, big box stores, and so on.

That’s a great point, hoping someone can explain it a bit further. Im curious is could Jack have lived past 100 without the weightlifting?
Thanks for sharing though. This was my question as guys like Steve reeves and reg park and all these body builders seem to pass early.

This makes a lot of sense, but how does that explain lemons and limes?

Reply to ELI5 How did knights participate in tournaments like jousting without killing themselves? by QuantumHamster
Professional football players and boxers have a 100% chance of suffering traumatic brain injury during their careers (literally--a study of the brains of deceased football players showed that all of them had CTE). They still do it. Money, fame, glory, the belief in young people in their immortality, are probably all contributing factors.
As in modern sports, medieval athletes took steps to protect themselves. The goal wasn't to kill each other. They wore special armor and used blunted weapons.
Of course, sometimes people died, but people die in modern sports, too. To say nothing of the severe and debilitating brain damage they suffer from repeated concussive injuries.

I have a feeling the fact that many people in the airport are about to spend, or just spent who knows how long in a cramped space, has something to do with the psychology of airport architecture.

I have it on good authority that the human body generates more bioelectricity than a 120-volt battery and over 25,000 BTUs of body heat.

Life existed before Oxygen was abundant, so no.
About 2.4 billion years ago, some bacteria figured out how to photosynthesise to get energy from sunlight. Photosynthesis produces Oxygen gas, which they didn't need, so they burped it out. Over hundreds of millions of years, the oxygen built up. Oxygen is quite toxic to life forms not used to it, so that led a mass extinction.

The problem here is you’re talking about to different things. Exercise causes cells do die, but because it damaged the cell. Aging happens because of changes to the DNA, not the cell itself. Basically with time, DNA changes and gets bad at replicating (telomeres shortening), so cells don’t replicate and create new cells as they used to. When exercising, you damaged cells, but it doesn’t affect your DNA, so it has no effect on aging. You’re fine!

They don't know. But plants that just so happened to produce sweeter fruit, (or peppers with more capsaicin) ended up having their seeds spread more, and so the next generation had a greater tendency to do that.

Biochemistry and organic chemistry in college! I don't practice chemistry in my job, but I remember enough to text basic concepts. I figured I could give a high level explanation here.

It was originally supposed to be for processing but someone decided the viewers were too stupid and changed it to batteries. Something like that anyways.
