I haven't been anywhere in a couple of weeks, except:

Last weekend, while my son and daughter-in-law were out of town for their first weekend away from the kids, #GS4 had a medical issue and I had to drive him to the doctor's office.

Thus, it is likely that exposure to the doctor gave me a cold.

It is getting better, and will probably be gone completely in another day or two.

The cold seems to have sapped my energy. I've been doing an hour or so of #DataCamp, plus another hour or so of #Coursera each night, but recently it is either one or the other.
