No.
A randomly chosen old person has more experience than a randomly chosen young person, by definition. Due to neural plasticity, a young person has more knowledge in every field that changes significantly over the course of a generation. I cannot discern a meaningful definition of "sensible" in this context.
I know this is a popular one, especially on Reddit etc to moan about - old people vote the most, but they don't like our drugs, gay marriage etc
But the fact is old people have more experience, more knowledge, and are just far more sensible. We'll all be there at some point.
