Keeping Afloat

To help prevent that sinking feeling

Whether we indulge in hang-gliding (not that I would ever have done that let alone attempt to do that) or relish the feeling of near weightlessness during a dive (which I did have experience with), nobody can really escape gravity on Earth. Staying afloat (in many ways) is staying alive. This holds true even for the smallest forms of plankton: without certain specializations to stay afloat they would all gradually sink to the bottom of the sea. Dead fish only float at the surface as long as their swim bladder is still intact – once ruptured they, too, sink. —>—>
