Over ten million gamers watch Tom Cassell's every move on YouTube. But now he's taking things to a new level. After losing his grandmother to ALS, he's doing what he can to raise awareness and find a cure.
"The more people know about it, the more people want to get involved with it," Cassell explained.
He's traveled to Columbia University Medical Center in NYC to help researchers reverse the disease's deadly prognosis.
"What gets me into the lab every day is hopefully changing that," he added.
Tom is on a new mission: helping fight ALS.
