Amontillada:

I'm not sure, but I have an impression that has more to do with their
tendency to fight and harm each other, not with early death from
natural causes. If many giants die young from battle or injuries, it
would reduce the average life expectancy.

 But JKR said

Amontillada:

I've wondered about that assumption. It may be that McGonagal chose to
leave the headmaster's office and return her energies to teaching. A
teacher with her great skill at Transfiguration may be harder to find
than an able headmaster.
