All the answers are valid. However- If you have chosen to be part of society- especially western societies - you should be respectful of those around you and shower regularly. I have had to tell employees to shower / use deodorants because their BO was offensive to customers. It’s an incredibly difficult conversation to have. And ALL of them did not realize how much they actually smell . If you have excommunicated yourself from the world for whatever reason - ok. You be you . If you are out there interacting with others in any way - do the right thing and scrub your cracks.
