If the medical community came up with an immortality regimen tomorrow, would you do it?

i would still have children if i could find a wife, yes.

but i wouldn't take any regimen. namely because i would hope for a better resurrection rather than take the risk of an undocumented medical risk, where the body dies and the mind goes to dementia

i like to think of the movie Zardoz with sean connery.

counterfeit immortals who desire to hire a warrior to kill them all

No I wouldn't go on the regimen. I'd have children and try to convince them not to take it either.

Hebrews 9:27

And as it is appointed for men to die once, but after this the judgment,

No. Who wants to live forever? Especially on this rat-ƒu©ked planet?

Not a medical limitation, but one of physics.
