This is just a restatement of what you said in your first line, but again it's just an assertion: "they won't do it" - well okay, why won't they? Is it because they feel they don't have enough time? Then we must give them more time. Is it because they have little regard for their mental health? Then tell them the dangers of letting mental health go unchecked. Is it because they are averse to it because they see it as a satanic ritual? Then we must educate them.
