The logistics of avoiding infecting others or being infected are astounding. Ideally, you have enough food, other essentials and money to live on for as long as it takes, and don’t need to venture out. You don’t have to worry about alternate side parking, walking the dog or mowing the lawn, because these don’t apply to you. But, you still have to take out the trash and put it in something, pick up your mail if you don’t have a slot, and get exercise, which is hard to do solely at home for most people.
These involve touching things that have been touched by others, thus taking precautions, plus risking actual contact with others. Of course, most people will have to venture out eventually to get perishables like milk, cream, eggs, cheese, produce, etc., as these can only last so long at home. Most will tire of packaged or home-cooked meals and thus will have to have food delivered or venture out to pick it up. Many people do have dogs that need to be taken out, kids who have to be taken out to the park for their and their parents’ health, and medical needs that can’t be dealt with solely at home.
And lots of people still have jobs that can’t be done from home. All of this will involve touching things and some human contact. Gloves and masks can only protect you so much, and you can’t wipe or spray everything you touch. Idiots are going to cough, sneeze and spittle-talk in your direction, and apparently the virus can linger in the air a while. There are going to be gaps in the various forms of protection people take, at which point it becomes a matter of luck as to whether your gaps will be penetrated by the virus, and if so, how well you’ll weather it and whether you’ll pass it on to others.
I guess this is what they mean by flattening the curve. It can’t be zeroed with even the most stringent measures conscientiously observed (which of course will never happen, thank you spring break imbeciles and I’m young and healthy so I’m not worried twentysomethings), so the best we can do is lessen transmissions drastically, by lessening the chances of it drastically. But none of this is fool-proof, and some people who’ve taken every measure possible will still get it, while others who have been pretty reckless will not, or will but won’t suffer much from it. Who needs disaster movies?
