What if you had time shoes that make time slow down or speed up determined by your walking speed? If you did, are you concerned that you would also then stop time by not walking. So you would have to walk all the time to keep time moving. What about aging processes? Would you age more quickly than everyone else because time was not passing for them while you slept? Of would it be a weeping angels type thing where you stopped and could never start again because there was no time? How would you take the shoes off? Do they continue to work while not being worn? Like you take them off, and time is stopped and you cannot put them on again? What about hopping and jumping? What if you walk backwards, does time flow backwards? do they only work for you, or could someone kidnap you and strap you to a treadmill? Or worse, invent a machine to which they could attach your severed feet? What about hopscotch? What if you grow out of them? what if the laces break, does it make a difference? What if you walk sideways? or Moonwalk? How about sex? Would time go fast fast fast sloooow fast fast fast slooooow faster faster faster faster, and then you could pause just at the right time for like two or three minutes? Also, would you notice any difference? You are not exempt from the effect, or are you?
