Lighthearted of course! Just before getting in the bath yesterday, I weighed myself stark naked. I wallowed in the bath for about an hour watching tiktok, got out and weighed myself again, with wet hair and a towel on my head, but otherwise not a stitch on me.
In that hour I apparently lost 4lb
it's not the first time. Every time I have a bath I "lose" at least 2lb!
My only conclusion is that osmosis is taking place. Vaguely remembering my gcse definition, it's when water moves from an area of high concentration to an area of low concentration... so clearly I'm made up of at least 101% water
