@thaproffesor While its good to encourage each other certain hygienic standards, we also have to be empathetic about different cases. Some people have unsettled bowls, one may have running stomach. What should they do? Spend 9 hours at work while holding on? Emphasis should be on hygiene.
@SoulDeepZim I hear your point for assignments. I also cited just those ones because I am familiar with them, but trust me in Ireland there are a number of universities that do handwritten examinations.
