Wait for some stem cell therapies or other real aging-reversal stuff. It shouldn't take too long for the first ones to be available. Save your money till then (I'd estimate - 10-15years from now, and you may very well be able to turn back some aspects of your biology to a more youthful phenotype. I think - some organs, skin, will be the first. Later on - intracellular junk disposal therapies, mitochondria rejuvenation, etc... till aging will be a choice, for people with money.).
