>>12171053You must define stress first. Is it about oxidative/reductive stress ? Physical stress ? Psychological stress?
Stress is present in all living things. It has allowed us to survive in the nature, anatomical humans haven't been around for very long, and our brain hasn't had time to adapt to our way of life (Or is it the other way around?)
The answer is, funnily enough, coping more faggot.
Biologically you could create an organism insensitive to stress, mainly by disrupting the development of the amygdal or the cerebellum. That is being said, we do not really know the gene involved in the development of these structure.
Another limitation would be the behavior of the resulting organism. Without stress, it would be quite hard to have this being experience self preservation.
