Man made protections that most of us have been using lately amid the COVID-19 pandemic are masks and rubber gloves. Technology used would be screenings with touch less thermometers and answering questionnaires. Laws among the COVID pandemic would be mask mandates that took place for awhile. Although some states, including Texas are starting to lift these, they were still in place and a govern give protection. I use all these in my daily life for work. I work at a daycare and it is crucial that all the employees and kids have screenings, wear masks (if over two), and wash hands frequently, etc. There is a risk everywhere you go, but a daycare has young children who are not always capable of not being super spreader. As they have runny noses, cough, etc. especially babies, they rely on us to care for them. How this relates to the brain is that COVID can cause headaches, brain fog, and rarely brain issues.
