Given the appointment age of most justices, 20 years and life aren't much different.
The last 4+ justices appointed were in their 50s. Gorsuch was 50. A top name on the short list both times was Amy Coney Barett, 48. They've been grooming a 38 year-old, Justin Walker, for the court. He went from a few months of litigation experience to the federal bench to the DC circuit in a year.
Notice how all these people also look very healthy? They're trying to get people who will last a lot longer than 20 years.
