Basically follow the same healthy habits you would employ if there were no lockdown. asanelderly geezer, I have been staying home for the last several days. I have been exercising (yard work and a stationary bike -about 45 minutes a day). I try to eat healthy stuff and lay off the booze (easily accomplished).
If I didn't have the bike,I would run or walk around the neighborhood - just maintain social distancing.
This is also a good time for those rainy day projects...
one or more gifts or other benefits from the co-op.
