The correct answer is that they only take make-up exams and nothing else that might not be a part of their job. They don't have to take exams on things that are not related in any way to make-up or the make-up industry or similar things. It's only for those who are into make-up.
For the people (and we shouldn't be thinking "them", but "us" - we all hope to be older one day!)
this means a better quality of life when old, and also potential longer life and longer health: with more social stimuli, the brains will be longer healthier
For the society:
lower costs of care (since the elder will be longer independent) and the possibility of benefiting from their experience!
