I just bit my tongue so hard I saw stars.
The conversation was with a 70 -year-old salesman who came to see my boss, and I greeted him as I was getting ready for my workout. On his way out of the box, he said, “Be careful.” I responded, “You too,” hoping he would spare me a lecture. He (unnecessarily) clarified, “Lifting weights. It’s dangerous for you.”
Then he went on to tell me about his pacemaker.
I let him go without a lecture.
