I’m a right footed person. That’s why I picked my left leg.
right leg. I got a left-footed soccer leg right here, but, i couldn’t kick really well on a wheel chair now…
I’m thinking, how could you play soccer with only one leg?
it would become something like a wheelchair hockey then, you would use a stick to move the ball or use your only good leg to kick.
My right arm…the reason being that it’s already somewhat damaged from a horrible incident when I was a child so it’s my worst limb and therefore the one I’d rather lose over the others. Not to mention I like to walk and it’s easier to do that and stay in shape with both legs I think.
Interesting choice.
Here’s a related question- Would you rather be Deaf or Blind?
Deaf, duh! How could you watch Pixar films if you were blind?? 
Haha, but yeah, I would also rather lose an arm. I’m a snowboard instructor and boardsport enthusiast, and I couldn’t do the things I love the most with a prosthetic one. I can relearn a lifestyle with only one arm.
That is a hard question but I would say leg. Because pretty much arms do everything.
My right leg. (goes on eBay looking for wooden legs)
