Ecto-kids and thresholds

I think ectobiology removes your limiters

Think about it

John was expected to lift a safe and wields massive hammers
Rose is a super genius
Dirk can flash step

I think ectobiology gives you super charged evolution so you grow into what Sburb wants

If you are kinda good at something, through Sburb you could be beyond human limits

(If you ever worry about failing Sburb, just remember you would be superhuman)
