I have seen people do these exercises and I know they enjoy them. I'm sure many people think I'm nuts. Shortly after we were married my husband bought and 18.5 foot v-hull boat with a high-powered outboard without discussing it with me. He assumed everyone grew up enjoying the water because he grew up boating and fishing. I was so scared I had to crawl on my hands and knees down the dock to get in the boat. Once I was in I hyperventilated and got nauseous. We didn't keep the boat long. I am petrified of water. We have friends who have pontoon boats and have invited to go for a ride on a nearby small lake. I made up my mind I was going to do it but after crawling down to boat I got so dizzy I couldn't stand up. I might be able to walk in ankle-deep water but once it gets knee deep I feel like it is sweeping me off my feet and panic.
