That’ll never happen, too easy to fudge. Worse, as medical technology improves lifespans increase. By 2100 (if we’re still here) we could potentially have people 150 fucking years old or more in politics that started at 30. You think some old, rich bastard 50 years out of touch is bad, wait until that old, rich bastard is 100 years out of touch. Or 200. Or fuck knows how long we could drag this shit out for if you’re rich and powerful enough to get the longevity tech, medicine, etc.
