Nose-picking is a common and well known socially condemmed habit.
However, this condemnation seems to be a purely social behavior with very little grounds on medical risks; it is even done by other species, see below.
- can we set a time of when it started? (10.000 BC, 0 AC, 1000 AC?)
- What are the first documentations of nose-picking?
- Did this behavior appeared independently in different cultures or was developed by one and then "imitated" by others?
