> My body is designed so that it can do this. Hence, not having children is against the design. Your body is also designed to age and die, by the way. What is the reason to follow that design, anyway? Why not change it to serve your own interests better? > I do want to have a health span (not life span) So why exactly would you like to die?
> Your body is also designed to age and die, by the way. What is the reason to follow that design, anyway? No reason. I must. I am sure tech is here already to rise babies externally. That still doesn't change my design to want them because of feromones, reproductive system etc. When we are able to change that design (via viral patches for example) then we can talk about alternatives. > So why exactly would you like…
You're a conscious being that has free will. Technically, the only thing you "must" obey is physics. Our ability to override these animalistic instincts is one of the things that makes us distinct from animals.
Besides, making life-changing decisions with "no reason" is... I don't know... irresponsible with regard to yourself?
> That still doesn't change my design to want them because of feromones, reproductive system etc.
This doesn't make you want to have kids. This makes you want to have sex.
> Like I said, health span. That is achievable nowdays.
I don't think lifespan and healthspan are separable like you suggest. How do you even imagine that? A 30-year-old-looking person in perfect health just suddenly dying (of what?) at the chronological age of 90? That's not how this works. People die "of old age" because, well, they age, and their health declines as they age. If you don't age, your risk of death doesn't increase. That simple.
