The actor (left), pictured with his son Redmond (right), has had a stressful few years.
In 2001, he battled leukemia, and in 2009, he lost long-time partner, Farrah Fawcett, to cancer.
The actor has also reportedly struggled with drugs, and in 2008, he was busted for drug possession.
All that stuff sure does take a toll.
