Tennis is good for your fitness and it beats other sports like OP mentioned. It's a rather harmless addiction and one that rewards you with a lifetime of fun.
If you consider $100+ racquets a cheap addiction, I'd like to know what you consider expensive
Racquets are an awful lot like cars. The second you drive a car off the lot, it loses 20% of its value. Same the moment you string and hit with a racquet for the first time. As I've discovered when I tried to re-sell my "demo" frames (which I usually bought in "slightly used" condition).
I agree that tennis itself is an expensive and harmless (indeed, beneficial) addiction. But continuously buying and trying new racquets? Neither cheap nor harmless (as my wonky strokes will attest).
