Minus the seizures thats my life to.
But thankfully IT stuff is my biggest hobby so on good days I program a bit. On bad days its video watching. Some gaming, messing around with operating systems.
If its physical limits but your mind is clear then philosophy is also a favorite of mine. Just think of something you have no answer to that is fun to think about and see whats most plausible.
I came up with a completely new education system, a new migration system and my own specation on who created the universe that way.
