PTL! Glad your brother is doing better. And thank you for the post. You just solved what happened to my FIL several years. We were fishing in a small local lake when I realized that I hadn't heard him whooping it up catching crappie. I turned around and just barely kept him from sliding out of the boat. Thought he was dead. Called 911. Ambulance and Rescue were there before I could get the boat back to launch site (less that 500 yards) with trolling motor on high. Big husky rescue fella reached in the boat and jerked him out and threw him up on the bank. When his head hit the ground he opened his eyes, drew a giant breath and wanted to know where he was. Hospital couldn't find anything wrong. Kept him overnight and sent him home. He was 83. Have always wondered what happened. Now I know. Thank you. And may your brother continue to do well.
