Make myself slimmer and try to give myself a Wolverine level healing factor.

Imma modify my body to give myself my favorite appearance, voice, height etc Then, imma go far into it and try to give myself superpowers of any and every kind. Imma constantly modify my body 24/7 to give myself as much powers as possible to try and be as OP and versatile as possible.

I make my whole body impossible to be permanently destroyed, as I can regenerate from nothing, and my dead cells can move and function like living cells but without flaws and limits of one as it is still dead. The dead cells can also multiply and grow, and can only stop if replaced by living cells, or just simply being healed over. This is because you can't kill what's already dead, so there is precautions to prevent anything that proves the statement wrong. Anything that suppose to be instant death would be treated as a simple cold. Any damages to my brain would do nothing to my mind, even with my entire head gone, my mind would still exist and continue to work without the need of having a brain. Also no matter what condition with my heart and blood will not impact my body and life. I also gain trait of aging between 25 and 50, so when I eventually hit 50 I reverse-age back to 25 then continue to age again to 50, a constant loop to experience youth and maturity.
