live

Maybe it's related to the length of gestation?

raise their young...in the case of humans, they may *never* leave home!

Live

Agree with LoneJack - lifespan increases.

Eat?....grass eaters/herbivores spend a lot of time eating....

I agree with Annie - raising their young. Of course they have to live longer to do this as well. Animals like tortoises and parrots live pretty long with small brains.

tend to their young

sleep

Be head of the family

Search for a hat that fits ...

The larger the brain, the longer the gestation period.
