Yeah, I've heard this rationale as well, but for men my age, household accidents make up most accidental injuries and death. Of course the majority of household accidental injuries and deaths are caused by poisoning. I am not sure how that sort of thing happens, but perhaps that includes drug overdoses? Otherwise I am not sure how so many people are poisoning themselves.
On the other hand, perhaps it is not necessarily "accidental"
In any case, if you factor in the decrease in traffic on the road and as long as you are not engaging in particularly risky activities, I am not sure how taking a road trip to a deserted national forest is any less safe or more taxing on our medical infrastructure.
Currently we are taking daily walks around the neighborhood and I am more concerned about breaking my ankle while dodging the crazy drivers texting on their phones than I am breaking my ankle at my favorite campsite in the Sierra National Forest.
I'm not saying that everybody should just ignore the SIP orders, but I am pointing out that somebody can hurt themselves just as easily working on their truck in the driveway at home as they can setting up camp in the woods. And there are communities around here that are smothered right now and I may hazard a guess that Kern County might be a better place to have an ankle cast at this point in time.
