Age categories.

Sorry if this has been asked before but I was wondering what tje age categories for the bps sre?
like how old is considered juvinile?
sub adult?
adult?
geriatric?

I looked to see if there was a thread like this and couldnt find one. Any replies would be appreciated.
thank you :)

I would consider juveniles to be less than a year, subadults from a year to breeding age, and then they are adults. I am not sure where geriatric starts, they can live 25 plus years.
