    Human body from birth to age 29: I am invincible!

    Human body once you hit 30: Hey, remember that time your knee was sore for an hour when you were 12? Well now it’s gonna be sore for the rest of your life

        It’s highly innervated (sensitive) and it’s cartilaginous. Cartilage is mostly nonvascular, meaning that it doesn’t have blood flow to it, and which also means healing takes forever.

        Because it tends to hurt for a while due to the actual physical trauma, our nervous systems also tend to send the pain messaging well after the actual trauma, even if healing has taken place. This specific pain presentation is a form of chronic pain (mostly a nervous system disorder) that is usually onset by some sort of physical trauma.

          Not my tailbone, but my hip, specifically where it joints with my leg. Fell while ice skating once as a teenager and every couple of years since I’ve gotten sharp pain in that joint that makes me almost immobile for a couple of weeks. Best I’ve ever gotten from a doc is a steroid shot to “hopefully” boost the healing.

          Hasn’t happened in a while… knocks on wood.

            That most likely is due to you being fixated on your thumb. We can and do consistently wire our nervous systems, and in this case you’ve probably wired yours to produce a pain sensation in your thumb.

            In a nutshell, this is how chronic pain works. There most likely is nothing physically wrong with your thumb.

    One is a requirement to be an organism. The other is a nice to have. A great many creatures simply die after reproducing, for example, which we can interpret to mean the minimum requirement has been met and anything beyond that isn’t as important, if we like to view it that way.

    Forming that small person is also a bit of a chaotic and messy process involving chance errors of various kinds and variations in the way parts grew. In a sense, the person formed would never be exactly the same if you tried again with the same inputs either.

    That this system works as well as it does is a miracle.

    EDIT: Missing words.

      Octopi are these incredibly intelligent and exceptionally resilient, but they kick it inside 3-5 years, typically right after reproducing.

        Sounds like they should have made their kids’ survival dependent on their survival. That’s the ticket, right there. Now we just need to make our great-grandkids’ survival dependent on our survival, and we’ll all be healthy right into the next century!

      I feel like once you hit your 40s, you really start to understand that concept of your body only being evolved enough to ensure that you can reproduce and the next generation survives.

      In your 40s and you hurt your knee? Fuck you, your knee now hurts for the rest of your life - why aren’t you dead already?

        This makes me wonder; why then would women typically have longer life-spans then men? Once women hit menopause they are biologically useless for propogating the species whereas men retain the ability impregnate women for their whole lives.

          I think, that having purpose in life helps, and women tend to prioritize social connection from a very young age, therefore they are on average more connected and that helps in finding purpose. The rest is pure force of will to fulfill the purpose

            I feel like this is closer to the reason why suicide is the #2 cause of death for men from like 19-49. After that diseases start to overtake it a bit. Car accident is #1, in case you were curious.

          Grandparents are valuable, and women tend to be smaller and require fewer resources to provide wisdom and babysitting.

          I saw something that mentioned having 2 X chromosomes is beneficial. Something about redundant copies of DNA which helps prevent some problems. I dunno, I’m not a scientist.

          Can ask the same about men. Orcas have menopause. Female orcas live somewhere between 60 and 90 years. Male orcas only 30. Also… post menopausal orcas pimp out their sons. Imagine your mom as your wingman.

          We live so long because we rely on experience. Menopause (and andropause) are just ways to make sure the parents don’t compete with their offspring, but stick around long enough to help.

          Death and aging is needed to make animals stop reproducing. This is because the only way we can adapt to changing enviroments, is through having offspring with a mutation that is hopefully useful. Lots of algae, fungi, bacteria don’t have this issue. They can just transfer genes they developed/found to anither member of its species like it’s christmas. No need to die if you can just adapt your own genetics.

          Menopause (and andropause to a lesser extent) is our copout and allows us to live longer.

          There is more to evolutionary fitness than reproduction, though that is chief among the desired traits. The gathering / providing of supplies and wellbeing of the home are also up there.

          Not to mention, wrt reproduction we need all the women we can get. We need only a few men. One male of a species can keep an arkload of women pregnant at a time.

          When my son was a toddler, he went down a slide feet first but on his stomach. I had a complete brain fart and forgot to catch him at the bottom of the slide like I had always done in the past. He few about 3 feet, then landed on the ground on his stomach, his head whipped back and then slammed face first into the ground.

          I remember thinking at the time, Jesus Christ, I would be DEAD if that happened to me. But yeah, he cried a little bit and walked it off.

      Something the OOP also forgets to take into account is that a LOT of pregnancies fail. Especially in the early stages, before the pregnant person even knows that they’re having a miscarriage.

      The efficacy of taking collagen specifically is very much in question. It seems to be about as effective (but much more expensive) than just increasing protein consumption.

      There are things you can do, like apply heat and to an extent certain supplements can help (glucosamine and turmeric are the notable ones that have evidence to support them). That said the main thing that really helps is doing dedicated and systematic strength and mobily training for your ankle.

        What people tend to forget about infants and small children is that they are constantly exercising, eating a ton of calories, and then getting tons of sleep.

        Adults, by contrast, tend to be very sedentary with slower metabolism and a ton of anxiety from stimulants/stress that prevent long, regular rest cycles.

        Also, incidentally, if you really want to fuck up a child early in life… Malnutrition, immobility, anxiety, irregular sleep cycles, and lots of stimulants (particularly cigarettes) will have your teenagers looking geriatric.

          Probably that’s a combination of placebo and the result of the fact that collagen is a protein supplement. You can most likely get the same result by using whey or other proteins for much lower cost.
