...would you travel from California to Maine, on foot, no vehicles whatsoever, and without the benefit of housing? You travel from one end of the US to the other, camping out or sleeping in alleys. You can't sleep indoors, and that includes mobile homes. Tents are allowed. Your safety is not guarranteed, so it's up to you to be cautious
...cross a bridge between two 80 story skyscrapers? This bridge is 2 feet wide, with no rails or walls. Just a long plank, that extends about 100' between the buildings. It's strong titanium, and will not collapse under your weight. You'll have to make it across this bridge anyway you want, but you can't use safety harnesses or other safety gear. Realistically, do you think you could do it?
...push a felon into a pool of starving piranha? The felon is a serial rapist, and he's standing there, shackled, at the end of the pool, begging for his life. You just have to lean in and push him into the pool of famished fish, who will devour him quickly. He raped like 30 women, and is far from innocent, and the world would be a better place with his absence, but do you have it in you to kill?
...change your clothes only 12 times in the next calendar year? You can only change your clothes/outfit on the first of each month, and then the remainder of the month, you have to wear that same outfit. No matter what happens to your clothes, no matter how dirty it gets, no matter how unhygenic it may be. This includes underwear. You can bathe as normal. You just can't wear anything else but your chosen outfit, until the first of the next month
...have all your toes amputated and replaced with prosthetics? All of them. The new toes will look normal, but they'll feel different, kinda rubbery. Just how attached are you to your toes anyway?
Edit: You can't wash the clothes
