Very good advice.
Two years ago (in Australia), a father and son died at a lake near where I work. They were out on a boat duckshooting. When the news came around someone sighed and commented "I bet they didn't have their life jackets on."
They didn't, and the apparent reason was because they often went out there, and it was very familiar to them. So they forgot the risks.
Everyone must be reminded of the risks, like in your post.

Good point.
