>The word Senate is etymologically related to "senior", it's a place where you _want_ people to be able to develop a lot of institutional experience.

I’m not disagreeing with the rest of your comment, but I’m going to challenge the notion that this etymological connection carries meaning. The word comes from Roman Senate, and in that context in Latin “senior” really meant people with higher status rather than age. Latin is full of these weird double meanings. Compare to seigneur in French or señor in Spanish. Also, the House of Lords in the United Kingdom.
