lockdown brain
This is a state of mind in which you are confused, foggy, forgetful, and basically incapable of putting two thoughts together. The reason is that humans need sociability to keep their brains active. The reason for the craving to party is that we feel our mental acuity slipping away from us. It’s as good a reason as any, although sadly we must resist and resign ourselves to having a mind like soggy toast for the time being. At least we now have something to blame, whereas before we might have been yelled at for being stupid.
Some remedies have been suggested. Take up ballroom dancing with your partner and follow one of the instructional videos. Relating to the teacher helps. Likewise exercise routines. Try zooming. It isn’t very satisfactory but it is better than nothing. And try to make each day a little bit different in some way so that you can tell which day it is.
