Not yet fallen

It is past peak fall colors, and most of the leaves have fallen. But this tree I saw on my walk is still hanging in there will its brilliant red leaves. I walked about a mile (1.6 km), some of which was uphill, to try to get some exercise in.

My doctor is starting me on a low dose of blood pressure medication. I wonder if COVID has anything to do with this, because my blood pressure was normal when it was measured before that.
