What is this bottle of Aether for?

Hey all! I found this bottle in the cabinet, can anybody enlighten me as to what it would be used for? I can see online that its an anesthetic but why would someone have that at home? Is it used for anything else? And if do how would I use it? https://imgur.com/a/qlbgxTb I am M27, 6'1", don't smoke, no medical history.
