"The median survival time for glioblastoma (GBM) is 14.6 to 18 months, and the five-year survival rate is around 10%." I had a friend who died from it about 2 years after treatment. 10 years is very unusual. Things don't add up and his wife having an affair with Hunter was cheap and tawdry. Hunter also had something going on with Beau's daughter. That family is F'd up.
