In a nutshell, a 72 year old deer hunter was separated from his hunting buddy and survived in California's Mendocino National Forest on his own for 19 days.

The article is light on details, but he did several things right: After realizing he wasn't going to find his way out, he stayed put. He knew he couldn't take a deer so he worked on smaller game, including squirrels and lizards. He made a fire. He packed his clothes with dry leaves for insulation. He made himself easy to find by calling out for help. Most importantly, he never gave up.
