A 10yr. can then anyone can

As we this 10yr. old is being sworn into the Army. This young boys name is Brennan and he has terminal cancer and this was his last wish, the army granted this . Brennan has been an Army lover since he can remember, he has a facebook  page for all of his fan named Brennan's brigade. A charity called DREAMS Come True of Louisiana aparently had part of making this happen. So i think if this 10yr. was able to join the military and had the courage to do so. Anyone can do it.
