Last week a group of friends planned a paddling trip for today. All dropped out except myself and wife in a canoe and one friend in a kayak. Two dropped out because they said their knees and hips were hurting so getting in and out of their kayaks is getting too difficult. We lost two friends to the same complaints last year. I tried explain how much easier it is to get in and out of a canoe but didn't get any converts because it takes skill to paddle a canoe and none of them are sufficiently interested to learn something new.
