Dr. Vasul Raja and Munnah Bhai

I wanted to draft this better but couldn't :(
A few years ago I saw a reasonably well made Hindi movie - Munnah Bhai - by sheer chance. Soon it was remade in Tamil as Dr. Vasul Raja.
The movie shows the hero hugging terminally ill patients as he cares for them - he even cures a long term coma patient by being humane.

Just recently I stumbled upon this great TED Talk by Paul Zak on Trust, morality -- and oxytocin

I now wonder what the scriptwriter would say if he learns about this!
