I have a number of "alien" species that each excel in some small way (increased strength, eyesight, etc) so I wanted the humans in this universe to have faster than average healing.
I'm thinking my humans could heal 33% faster than what we experience in real life. So a broken bone that would normally take 6 weeks to heal takes 4. A common cold that might take 14 days to clear instead takes ~9. That being said, these humans aren't all-around healthier; they're simply reaching the same result in 66% of the usual time. So diseases like chronic illnesses that don't resolve naturally would remain the same.
Would a 33% faster healing rate drastically change our society? Would we see longer life spans? Or would there be detrimental long term effects?
(I'm hoping to keep the societal effects to a minimum for the sake of the story so I'm willing to play around with that proposition if I have to.)
