I don't want to keep coming back to the topic but I re-read the post about Darren and hand-washing - I was slightly wrong. He says he only uses soap when washing his hands when changing faecal nappies because he 'doesn't need it overwise'.
So rather than not wash his hands, he just uses water. It's still bad though.
EDIT: I checked the date of the post and it's about this vlog and it's from 11:00 onwards plus it's not just Darren, it was Georgiana who said it first and Darren also doesn't use soap normally.
