Oldest Profession

It's sports.  Oldest profession.  I was about to say second most popular and profitable.  But I'm not sure that's true. Going  way back to the Roman and Greek games, right up to the present, sports has more fans and makes more money than sex.   When a tennis match can pre-empt a steamy soap opera, when sports stars  salaries are in the millions, it looks like sex has been replaced. I doubt that even the hottest lady of the night makes that kind of money.
