Causes of madness.
1)Being alone many hours causes alot of stress (especially when he was in Uganda prison).
2) If you add money and family problems you become (I saw him.compain that his family members don't contact him He had to initiate contact...maybe he got divorced)
3) Drugs.
I've seen my friends loose sanity from drugs,depression and stress,marital problems.
Solution is to always go out there and have a conversation with people exercise travel find something to do otherwise you will run mad especially when it's cloudy.
