I think it would depend quite a bit, but flight seems to be a pretty handy one.

What is one thing you enjoy about cold weather?

Snow!!!   I grew up in a place where we never have it, and I never saw it for real until I was nearly 30, so snow is always a completely magical thing to me.

What's the best or most interesting book you've read recently (within the past year or so)?

Teleportation. You can always be where you're needed, or where you want to be, no matter how far it is. 

Favorite species of pet animal, and why?

Bearded dragon - because they're as close to the real thing as you can get!

do you prefer sweet or savory breakfast food?

I prefer savoury to sweet breakfast food as a rule, though I wouldn't say no to pancakes of any sort. Normally I just have muesli with berries or a sliced banana and milk.  

Would anyone like to go back in time to visit some previous era, if time travel was possible?
