‘Young blood’ is such a grotesque thing. Gotta harvest the next generation’s blood so some crusty old zillionaires can extend their shitty self-absorbed existence.

Use placental tissue (or a tissue sample), revert to stem cells, migrate to heart cells and grow them in a tube, harvesting the blood cells periodically. Not there yet but give it 5 years maybe.

What is wrong with old zillionaires? You'll be old someday too if you're lucky (odds are against your becoming a zillionaire).

And why claim that a particular group of people (especially with whom you likely share very little) lead a "shitty self-absorbed existence"?
