That would explain a lot. It would tell us why women of a certain age continue to wear short shorts. It would account for the fact that a 70 plus Hugh Hefner type feels he is still romantically attractive to a twenty year old woman. And it would explain the endless reunion tours of rock stars.
It would also account for some of the bumps and bruises I encounter daily. No wonder I land on my butt trying to take the stairs two at a time. It's an activity any 25 year old would handle easily. And it's not my fault I approach cardiac arrest trying to complete a walkathon. What 25 year old wouldn't try to walk 62km in one day? And falling flat on my face trying to clear a doggie-gate? My inner self has a lot to answer for.
