I think, that everyone can be excited, but that the excitement can be displayed differently per person.
When I am excited I start hand-flapping and jumping and turning in circles an make some high-pitched noises, although I don't like high-pitched noises and I can get an overload from being excited, where I need to rest from afterwards.
I have not seen many adults react this way.
But in sports it seems like supporters show an extreme amount of excitement as well though I don't know if they start hand-flapping and turning in circles, but they do jump, but without the hand-flapping I guess.
