Man rows 1,400 miles up the Atlantic Coast for Alzheimer's

Lewis Colam is rowing 1,400 miles up the Atlantic coast by himself.

He's doing it with the goal of raising $50,000 to help find a cure for Alzheimer's disease.

The 24-year-old man had never rowed before. But now he's rowing 10-12 hours per day and sleeping most nights on his boat.
