I suspect (and I bet statistics will bear this out) that a similar comparison can be made with PFD's. How many drowning victims had a PFD on? Not many I suspect.

The same logic can be applied to whether or not wears a PFD while swimming in a pool.

This is not saying the risk in a pool is equivalent to the risk of a canoist.  it just is pointing out that line of reasoning does not hold water (pun intended).
