aggression theory

[snakehunter]

ok ive been sick at home for four days, and when your inside for over 96 hrs your mind wanders....trust me!

so i have a "theory" on why ETB's and such are notoriously aggressive. ive been told many times that holding a tree boa that is at a young age could damage the spine, SO by the time your boa is structurely safe to hold, it has had a year or two of little human contact, and is in a sense wild. at an this handleable age it does not recognize people or keepers as safe animals, and is defense because of our size.

does this make sense, or have i been taking too much caugh syrup?
thanx
