When you’ve done just about everything else, why not volunteer your time and go save an elephant?
“This is a volunteer project created as a result of the escalation in competition in natural resources between the desert elephants and human inhabitants of the northern Erongo and Kunene regions of Namibia. During the project, you will work with local subsistence farmers, building protective walls around their critical water sources while educating locals on how to manage conflict with the elephants. In addition, you will learn to track elephants, recording invaluable data on their movements and diet.”
And when you’re done with the ‘phants you can go rock climbing. A stiff climb here that some Patagonia folks did.
Or a more relaxing “climb” to see Bushman paintings.
