Staying Young

Would you be willing to cannibalize the blood of your young in order to stave off old age?
I’m ashamed to say I’m thinking of ways to do this without exploiting kids. I only have nephews and I would guess that the more DNA you share with the donors, the more potent the results would be. But what if their male hormones affect me as a female (i.e. become more hirsute, be prone to balding, etc.)?
