"Ramis, a longtime North Shore resident, was surrounded by family when he died at 12:53 a.m. from complications of autoimmune inflammatory vasculitis, a rare disease that involves swelling of the blood vessels, his wife Erica Mann Ramis said. He was 69."
So may have died younger than you would expect because they abused their health.
If it is any small consolation to his family, friends, and fans, at least his legacy was not dying too damned young due an overdose or addiction.
