With me it's the science of natural resources and their derivatives, with a strong emphasis on chemicals. Professionally applied over a lifetime focused on domestic & international commerce. These are things I will not be retiring from. When the ships get really big there will always be a situation where it's most valuable to have uniquely deep experience, now more than ever over a greater number of decades. Many other unrelated and unscientific things I will also continue for life as much as I can, but for work that's how simple it is.
