Hang on, so obviously this is a long article and I'm not a very patient person, so tell me if I got this right or wrong, but does this only work if you're 40 or older? So I can't stay in my 20s forever with this? Also why no mention of the immortal jellyfish? Instead of slowing/stopping aging, it can actually reverse it aging process, so if you could give that to humans, you could actually experience being an adolescent again.
