Walking stiffly around a stage with the stars

Come on, Buzz Aldrin.  Seriously?  Dancing with the Stars?  You aren't dancing, you're barely staying upright.  Yes, I've heard the "But he's 80!" argument and I dismiss it.  He may be 80.  He's still a bad dancer.  Face it, even for an 80 year old, he is a horrifically bad dancer.  Hell, for a 115 year old he's a terrible dancer.  He couldn't be stiffer if they surgically fused all his joints together.  But fine, with age so goes your limberness, flexibility, and nimbleness.  But does your sense of rhythm somehow leave you as well, because he has none.  While "dancing" he manages to suck the sense of rhythm out of his partner and the first three rows of the audience.  He's a rhythm black hole.

Why did he do this?  It's not uplifting or inspiring, it is just sad and depressing. Watching the elderly try something gamely and fail miserably does not inspire me, it reminds me that aging is irrevocable, inevitable, and destructive.  That's what I want from my prime time television.  Oh, he wants inspire people to support the space program?  Frankly, if this is the best we've got, an example of the kind of person we're sending out into space as a representative of the human race, maybe we should just keep to our own planet.  We don't want to embarrass ourselves galaxy-wide, do we?
