I wish I could detach my limbs. They're so occasionally annoying; like when you're trying to go to sleep and maybe your feet are hanging off the bed or distracted by the texture of the blanket, one could just snap off their feet instead. Rather than being agitated by the constant stimulation of an insect sting, one could set aside their arm for a few days while it magically, without any physical connection to your main body release its inflammation. If I find myself in a stuffy place like a crowded train or a movie theater, I could detach my legs so that both me and others have more breathing room.

in turn you should also be able to grow more limbs, the usefulness of having more hands is obvious, but how about more legs too would it give you more mobility? youd need a lot of coordination
