For more than 20 years, former San Francisco 49ers lineman George Visger has lived his life out of hundreds of small yellow notebooks. In them he scrawls the minutiae of his daily life: "4:45 am left house. 2 stops to find coffee and a roll. Paper work till 9:25. 10:05 Ed called."

The notebooks are the last vestige of his memory.

"I always have them. They sit in my back pockets," said Visger, 51. "The movie '50 First Dates,' this has been my life for 28 years. I get up in the morning and I have no clue what I have to do that day. If it's not written down it doesn't exist."

Visger said his memory began fading in 1982. During his brief, injury-shortened career playing for the 49ers, he said, a jarring tackle caused a concussion.
