Almost immediately, he began to feel himself de-aging.
Most of the wrinkles faded from his face.
He could feel the age coming off his body.
He felt himself changing.
He felt his chocolate brown hair turn a darker shade.
"Wow!" Joe said, as he felt himself shrink a small bit. "I'm getting younger!"
and he was.
Also, his clothing began to get looser. His pants slipped down a bit. His feet knocked about in his shoes. His shirt sagged. he saw his belly deflate, he started breathing heavily, and he was shrinking down as well.
He lost 1 year of age, then another, and another, and another, and another, and another, and another, and another, and another, and another.
