PHOENIX - If attitude is everything, David Showerman certainly has the right attitude. He loves to laugh and the jokes just keep coming.
"A glass half full kind of viewpoint is better than a glass half empty," David said. And it's that same attitude that's getting David through the biggest challenge in his life.
Five years ago he was diagnosed with ALS.
"I feel like today I'm healthy except I've got ALS," David explained.
Over time, the rare neurological disease will affect the nerves cells responsible for muscle movement. Eventually, things like walking, talking, chewing food and breathing aren't possible.
"There is no known cause for ALS and there is no cure at this point so ALS is 100 percent fatal," says Amy Frank with the ALS Association of Arizona. She says right now 450 Arizonans have the disease.
David can walk and talk now, but his house is already equipped for when the day comes when he can't.
"You got to be careful to not judge the other person because you don't know what they're dealing with," David said.
The ALS Association of Arizona is holding its Bite Night fundraiser Saturday night in Scottsdale at the Westin Kierland Resort and Spa. It's an event full of food and drinks benefiting patients with ALS.
