There are probably a lot of hybrids in the world. Possibly all of humanity. Kids have more environmental stress now than they did. I have seen some 17 year olds who look 35 and some 35 year olds who look 17.

I have also seen kids with super old souls and they seem to regress as they age. Strange to watch someone progress from 800 to 350 to 30 to 15. Then they wake back up out of the world having beaten their soul out of them and become 400 again.
