There are people who lie in the bathtub for an hour longer, how do you pass the time when you are in the bathtub?
I myself usually bathe for 45 - 60 minutes and watch YouTube on my notebook at the same time
I think about the world like that or deal with all sorts of things around me.
I can't do that myself, at some point I get nauseous from bathing and my circulation knocks down because too hot XD
I usually bathe for between 20 minutes and half an hour. In the meantime I don't actually do anything, except for airing:-) that is also good sometimes
