If you're immortal evolution will make you a primitive freak,
False! It would, quite literally, take millions of years worth of evolution for you to be very, visibly different from the others around you (and you're likely to die long before that without invincibility). If you do manage to live that long, then reconstructive surgery is an option.
Time will pass faster until you go batshit insane
There is a reason that time passes faster for older people, and that reason is a lack of new experiences.
Our brains lump together similar experiences and forgets or assigns so little importance to them that it seems as if time passes by quickly when you do things you are familiar with. Our brains also distinctly remember new experiences, first times and unique occasions.
And don't you dare be the dumbass who says that "everything will be familiar and similar at one point, because you'll do everything!" Because that's just not true. The world is fucking massive, there are billions of people to meet, hundreds of billions of new things to do and try and learn about and experience, you could have a thousand years and barely scratch the surface of all life has to offer; not to mention that in those thousand years, thousands of new goddamn experiences would be made available by the progression of technology, the advancement of the human race, etc...
No, time will not pass faster, you will not go insane. Unless you're having an existential crisis, but fuck that, you already chose this fate.
, if you have allergies, you'll have to put up with that shit for another millenia,
Medication.
assuming you age, you'll be one ugly fuck, assuming you don't age, you'll be one weird-ass baby, assuming you only age a bit, then you'd be considered a really strange 20-year-old when you're 70.
Read the goddamn original post Sentinel! You'd maintain a youthful body. Yes, you would change psychologically, to a certain degree.
But a large amount of the psychological changes in a person's being come from the physical progression of their lives, as well as their mental progression. If someone stayed in their twenties forever, they wouldn't just automatically become typical 70-year old men, they'd just be more experienced 20-year olds.
Also, once humanity evolves, you'll never have sex again. Despite what furries would have you believe, nature hates the fuck out of interspecies banging.
False, as noted above, haha.
It gave us AIDs.
No it did not! That was a myth spread about by a bunch of racist fucks who said that the reasons African people had AIDS was because they fucked a bunch of chimps.
You realize that it can also be spread by blood right? What do you think is more likely, that the Africans killed and ate some undercooked chimp, or that they got into a fight with one and got blood on themselves?
Or that they got a bunch of chimps and banged the shit out of them, thus acquiring their lovely monkey STDs?
