I was dancing and i felt like it was easier to move than usual, i just felt so light. wat causes that?

um it's obviously because you where sick and didn't eat anything so you where probally dizzy but sometimes that can feel like a high !! So light headed from not eating yourr whole body felt light!..and you probally felt good cuz you where in a high state ! ... And 4 the last question .. It doesn't matter you weight even though it helps not to be fat ... But it mostly have 2 do with how light you are on ur feet .. Most of the time a fat person is flat footed therefore not light on his/her feet but you can be a lil big boned and still be light on your feet ... Like hip hop dancers they like girls with thick thighs and big butts !! But the can MOVE because they are light on their feet ! ... Ok hope I explained it to your likings !
