The median age of the House is 57.5 years old and the Senate is 64.7[0]
Its really not great. There's very few representatives that have any life experiences of someone in the 30s or 40s. I'd argue that makes them out of touch on a host of very real, very pressing issues.
The other thing to think about is the age of those with the levers of power. Its one thing to be elected as a House member or to the Senate, its a whole other thing to sit on key powerful committees, be the leader of the party in the respective chamber etc. and the most powerful folks in congress trend into the 60s+
