Probably not a good topic starter?

But I'm not sure if this post is about dancing or video games.
My daughters, and granddaughter... have this video 'game'? I would call it a game but I'm not sure it is.... I think workout video may be more accurate... like a Richard Simmons workout video but with differences. You dance the moves you see on screen in front of a thinga-ma-jig... (a device that sees and registers your motions).... and THEN, you get 'judged' and receive a score..... so I think it's a game/workout video. But here's my point:
My daughters and granddaughter took dancing lessons almost since birth. Good reason, my sister is a dance instructor. They can now accomplish something that utterly amazes me. They can watch a dance routine, while dancing along, and memorize it completely on ONE go through - - they have it down pat. And I'm not talking ONE routine here, or even two, not even 6. Dozens of them!
And these are NOT simple routines.... like "Step up Step Down Step Up Step Down.. etc etc etc" for a minute then move on. (ala Richard Simmons). They are full dance routines.... I don't know, 50 different moves for each 'song'?
BTW, no, I don't participate. First of all I'm too lazy. Second of all I can't memorize the 3 steps to change the wallpaper on my phone. Thirdly - by not participating I can maintain my decree that "if I did participate" I would win, easily. - JamesJM
