Not a general reflection, but more proof (as if it was needed) of what incredible athletes we have in tennis.
I remember one year, I think it was 1983, in that Wimbledon played a PEOPLE'S SUNDAY. Connors was to play Rostagno and, as he was warming up in Centre Court, he took two racquets (his T-2000's) and started hitting forehands with both hands, simultaneously. One left handed FH, one right handed FH. They were almost identical. Of course, his two-handed BH was a disguised FH, but him being able to take the dominant hand off and still hit a solid shot was impressive.
