I have heard of such incident that you described, about a man that died in his car, though it is mostly common among the male gender due to all kind of pressure and expectations from work and family members.
It is getting worse these days due to hike in the prices of product and service making survival nearly impossible but the good news is we will always find a way to survive the current crisis.
Outdoor activities is definitely effective, it is something I engage in from time to time.
