Check bags are fun. I just make sure there won't be anything illegal in my check bag which is forbidden at a cabin of a plane. Just leaving things like scissors and such out of my carry-on things in order to avoid troubles with some certain airline, y'know.
There is no age, height, or weight requirement to skate. It is good exercise no matter what your age is. If you want to be competitive, most start young. But, I practice with many adult competitors.
