In the 1985 Ron Howard movie "Cocoon," a group of elderly adults discovers that a nearby swimming pool has the power to imbue them with new strength, enhanced energy and a more youthful sense of well-being. While the cause of their new lease on life turns out to be from another planet, it doesn't take alien technology to reap the benefits of your neighborhood pool.
