The new age of vampirism has truly begun. Telomeres are shared across cells even donated cells, blood is the easiest source of more telomeres marrow makes blood cells and this is the key limiting factor for age. There are individuals with telomeres 30x the normal length of their age it is a mutation most of these people require lifelong care and take 20-30 years before they can speak or walk, they grow extremely slowly because telomeres dictate much of one's development. In ages past they died young, this being a genetic disorder means that clones of such individuals could become blood bags or be raised on life support and harvested of marrow so as to reverse and halt the aging of the extremely wealthy. The human lifespan may soon be increased by 100s of years. In this context it may be more accurate to call the coming age "the new age of Kronos" As anti-aging procedures become cheaper and more "ethical" we will cross a line where educating a new generation is more expensive than reversing the aging of the most competent individuals and then making them pay on an anti aging loan for 30-60 years. A 220 year old billionaire is still going to prefer under 25 YO women; if the powerful can clone children and cannibalize their bodies for parts I don't think these people are going to hesitate about taking children as spouses. Shit's about to go sideways.
