Do I have angel wings that sprout from my back, or bird wings where they're attached to my 'arms', or do I fly with no appparent propulsion (like telekineticly)?
I wouldn't want bird wings even if I had hands.
Angel wings would be fine but would make getting dressed awkward, as well as lounging on a sofa, or sleeping on a bed or being in a crowded/cramped place.
Telekineticly would be best provided I could hover.
Otherwise I definitely choose running especially if I can run 25m/s.
Being able to run a kilometre in 40 seconds would be nice, but hitting a wall or a person could kill me or someone else. We are talking about running 56mph here.
