Assuming that your invisibility only works for you (ie not your clothes), then this would mean creeping around naked all of the time. Which begs the questions:

- What do you do if your invisibility fails?
- If you are sweating, would your sweat be visible?
- When you eat at what point does the food become invisible... after how many hours on digestion?
- etc...

I think I would have to go for flying.. it seems to come more naturally to me, and there are less drawbacks.

Also because the thought of swimming around in a pool with 11 other naked guys playing hockey kind of creeps me out. There are some people I would not like to brush up against.
