“One theory as to tennis declining popularity is that baby boomers who grew up with Borg, Connors, McEnroe, et al, are too old to play it anymore”
That’s it in a nutshell. Tennis is a punishing game, especially for those of us who never got good enough to serve, volley and pound groundstrokes without tearing up tendons and joints. After fifteen or twenty years off it’s hard to get interested in the latest generation of killer tennis bots. Sorry kids.
