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 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 a miracle.
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.
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.

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!
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
Does anyone else just want those bacta tanks that they had Luke floating in after his hand was cut off or is that just me?
I bet you could do some serious shit to a person if you had something like that. Just crawl back into this cyber womb and we'll get you fixed up in a week.
In Star wars that's because the journey that Luke Skywalker was going though was running in parallels with the first Irish King Nuada of the Tuatha de Danan, (in Welsh known as Llud) who lost his hand and his kingship due to the Irish requirement that Kings be physically flawless only to regain it with a hand made of silver that was magically attached to him.
If the bacta tank had healed Luke's hand then he wouldn't have gotten the cool robot hand which gave him a point of familiarity with his own cyborg father in their final confrontation.
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.
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.
