In his memoir, Against All Odds: Being a David in a Goliath World, Matt wrote about the health struggles his brother, Josh, endured throughout his life.

"Two years after me came Joshua, and again, Mom and Dad faced more childbirth trauma, because Josh was born with a severe heart and lung defect, which would ultimately take his life," Matt wrote (via RadarOnline). "Only this time it was the uncertainty over whether their new baby would ever make it out of the hospital alive."

Matt explained that Josh dealt with "severe heart and lung problems" his entire life and had "many close calls with death." He explained: "Many times Josh's heart and lungs have simply stopped functioning on their own, and on other occasions he's had seizures that would have taken his life had someone not been there to help him."

Tragically, Joshua died in 1999 at the age of 34.
