Why are people so obsessed with loo rolls?

Another lockdown another set of panic buying (Tesco’s now restricting certain items) but why loo rolls. As soon as there is a whiff of an issue and they are gone. Haven’t these people got enough? We have, for the last year, done absolutely nothing different and by the time we have run out there’s loads in the shelves. I get the flour and eggs whilst demand goes up to bake at home or whatever but lock down doesn’t make you shit more !
