I can understand why it must be very hard to find older women who are willing to fight and be filmed. As an aging baby-boomer, I can tell you that the body just doesn't respond, nor recover in the manner that it once did. I wouldn't want to fight or even wrestle someone my own age because I'd probably be laid up for a month. Just trying to water ski leaves me hurting.
In regard to finding women however, I often wonder what happened to a lot of the catfight queens from yesteryear (like the many Golden Girls: Connie Sanchez, Renee Vicary, Paige Russell, etc., etc.), and Candi Samples and Uschi Digard. Would they be willing to step back on the mat or in the ring? After all, they've been filmed and they were very accomplished. And guys my age would most certainly dig it. It seems like they've all disappeared. Women who were gorgeous in their early years often don't want to be filmed because they don't look like they did 20 or 30 years ago. Frankly, that's quite OK with me. I wouldn't expect them to look like they did at age 25, but women in their 50's or 60's can still be very sexy -- it's just a different look. Like I tell my wife: "you're just as beautiful as you were at 25, it's just a different kind of beauty."
She doesn't believe me, but it's true.
