Actually, the retirement age is a good idea, except that I'd make it 70 for anyone on the SCOTUS.    Congress definitely needs term limits, and it wouldn't hurt to have mandatory retirement ages for them as well.  No later than 70 (65 is probably better) for the House, but I think 75 for the Senate.    I think there need to be term limits for the House and Senate - I could see reasons for 2 or 3 terms, but I'd also like to see mandatory year limits on senators and representatives - like no more than 20 years in high office (except if they run for POTUS).  We need to stop the 40 years in office leaching off the public and selling out to the highest bidder.
