Martin Scorsese
The 'Goodfellas' director almost died in 1978 from drug induced asthma.
He said: "Misuse of normal medications in combinations [to which] my body reacted in strange ways. I was down to about 109 pounds. It wasn't only drug-induced — asthma had a lot to do with it. I was kept in a hospital for 10 days and nights, and they took care of me, these doctors, and I became aware of not wanting to die and not wasting [my life]."
