I had a 64 year old retired guy as a helper one year and he wasn't as quick as I would have liked but he showed up every day, worked safely and didn't complain. He also competed in triathlons so he had better endurance than most of the 20 year olds I had over the years!
I don't think I was ever called in to the office about our numbers and we got the packages delivered most everyday.
I'm wiht you. My helper last year was 61 and he is coming back this year at 62. But I had the opposite problem. I had to tell him to slow down. the third day he slipped on some ice and fell on his ass. I laughed at him (after I knew he was ok) and told him, "I bet you'll slow down now."
