Discovery Health in the Know in April

Discovery Health Channel is rolling out a Dr. Know marathon on Sunday, April 16 at 2 p.m. The nine-part series, featuring Dr. Paul Trotman, aims to debunk the medical wives' tales we grew up with. Can you catch nasty bugs from public washrooms? Is a dog's mouth really as clean as a human's? Dr. Know susses out the truth. The series rebroadcasts Tuesdays at 12 a.m., beginning April 18.
