You're kidding right? Madonna (on a bad day for Madonna) is still in better shape then ANY, ANY woman her age GUARANTEED! Honey.
I have the same genetics and work out with a figure like hers in my mid forties and let's just say when 18-29 year old girl find out my age they without exception are speechless and don't believe it. Can't find a girl within two decades that can hold a candle to my power, strength, balance, endurance where I live. Madonna would be right there and she's a much better dancer! Plus she's ten years older.
If Madonna's naked body was before you now I a can assure you, you'd be drooling in awe and beg her. Then she'd read your post, laugh, and move on.
Can't really convince us unless you post pics....8^)
The rest of your post I agree with.
