The higher you go on a mountain the colder it gets, northern europe is colder.

I am going to remove the post though I don't want anyone to be offended or find it as a way to justify their racism

It wasn't meant to be rude I am italian by the way

It depends, imagine I also have a bad mutation, it might make more sense to let others spread the genes

I don't want to bother you because you're clearly uninterested but all I am saying is that keeping our body and memories is not enough to be immortal, it's not even the main requirement, you need to believe you always had that body or memories.

One could potentionally accept to be reborn in a new body with a different gender. If you don't have kids it simply won't work.

Even your past self isn't living if you think about it

If you became immortal but had total amnesia every 100 years, you could keep a diary and still feel immortal. If you got a new body every 100 years, you could tell your new body their past life and still feel immortal. But if the new body felt like a different person each time, you would not be immortal anymore.

But it requires serious coordination, a product/service that was effective would wipe out the competition

Lottery tickets are incredibly overpriced for the chance they give you. Don't just downvote me, show me a lottery where the price of the ticket is lower than the expected win (probability×jackpot)
