You got a body and I got a body and When we get our bodies together mama, we partyin' Reproducin' to keep it movin' Doin' our bit for evolution You got a body and I got a body and They differ – Mine'll probably fall apart quicker I'm talkin' ten years not ten seconds You and me baby, all the way to senescence I just wanna be an aging B-Boy Live long and prosper, Leonard Nemoy When it comes to longevity we're killin' it Life span longer than a Asian elephant Chimps get jealous at us, their close relatives We live like twenty years longer, Deal with it If you look elsewhere though, We're dead frail I want two hundred years like a bowhead whale! Aging and senescence aren't the same thing Aging is time passing, That's a great thing But senescence is bio-degrading Sucks to be a mayfly on the day of mating Time's wasting, Evolution tracks it Never puts all its eggs in one basket Longer life is better when predators are scarce 'Cause you can invest in care But when the dangers of death surround you Reproduce faster when hazards hound you This is how our bodies got built To achieve just one thing, And it's not health You got a body and I got a body and When we get our bodies together mama, we partyin' Reproducin' to keep it movin' Doin' our bit for evolution You got a body and I got a body and They differ – Mine'll probably fall apart quicker I'm talkin' ten years not ten seconds You and me baby, All the way to senescence I love your body mama, it's hella fine Even if it's kind of unintelligently designed Even if it's chock full of flaws, You're workin' it Let's be flawed together, Like other vertebrates You're hot, Even with your blind spot Even with your optic nerve tryin' to block Your retina, That collection of blood vessels is odd You're hot, But you're no cephalopod You're flawed, But I'm so flawed too My throat is designed so I choke on food The principle should be blatantly obvious Don't put the trachea in front of the esophagus! You can see why that's quite senseless Passing every bite over your windpipe's entrance But these bodies never had a blueprint Just generations and generations of evolution Perfection of design, That's irrelevant We take what we can from our past development Even if it leaves us vulnerable So here's what I wanna do before we gotta go... You got a body and I got a body and When we get our bodies together mama, we partyin' Reproducin' to keep it movin' Doin' our bit for evolution You got a body and I got a body and They differ – Mine'll probably fall apart quicker I'm talkin' ten years not ten seconds You and me baby, All the way to senescence Why don't our bodies regenerate better? And stretch out the lifespan like a tape measure? Why would evolution let us deteriorate And shape us into physically inferior apes? In old age, pulmonary disease Cancer, cardiovascular, diabetes Neurodegeneration, heebie jeebies Can I get some extra time if I eat my wheaties? Or at least an explanation That might help us one day to treat patients? Here's how George Williams might approach it Genes are antagonistically pleiotropic Their effects are quite various Some are beneficial and some are deleterious But if a mutation conveys a benefit Early in life, but then messes up the rest of it Helps an organism reproduce, And later brings on the death of it, Natural selection will select for it And that's how senescence got built in To our genome, now, speaking of children... You got a body and I got a body and When we get our bodies together mama, we partyin' Reproducin' to keep it movin' Doin' our bit for evolution You got a body and I got a body and They differ – Mine'll probably fall apart quicker I'm talkin' ten years not ten seconds You and me baby, all the way to senescence
