Your Brain on Scuba:
Scientific Proof That a Diving Vacation
Is Good for Your Mind — and Body, Too
There's a growing body of research in both the medical and psychological worlds that's exploring the health aspects of recreation, as well as the mental stimulation we get when we're having fun. The benefits of play include lowering our stress as well as fulfilling our brains' ingrained desire for, among other things, finding passion in our experiences. But each requires that we completely rethink how we do leisure, and while it may not be easy, it could be a lot of fun to try.

Getting the Drift:
A Diver's Guide to Drift Diving
Drift diving is just what you'd expect. When current is present at a dive site, instead of having to return to the entry location at the end of the dive, you drift along with the current and exit downstream. Of course, flying through the water column like flotsam does require some prerequisite knowledge and skill to ensure that drift dives are safe and enjoyable.

The author offers tips on how to avoid serious weather-related danger on the open seas.
