Question

On September 19th 2027, will the son do more push-ups than his father?

Background

The son is a middle-aged man who is recovering from a deltoid injury (left) and forearm injuries (both sides). 18 years ago, the son could do 60-65 push ups consistently. Currently, the son can only do 13 push-ups pain-free.

The father is ten years younger (being a father is more about the relationship than biology) and is free of injuries. Currently, the father can do 16 push-ups.
