Will spirits be able to do things that humans do, even though they don't possess the weight or m we do?

In other words, when a human does some ice skating, like in the 2010 Vancouver Olympics, for instance, uhm, a human skater relies on human qualities, such as gravity and weight and muscles and balance, all things that are distinctively human. Now a spirit will not be bound by these things, and is presumably following some other set of laws, so my question is, isn't it sad that a lot of the things that humans can do, spirits will not be able to recreate fully?
