Who retire the Supreme Court at 82?

Justice Ruth Bader Ginsburg retired from the Supreme Court at the age of 87, not 82. She served on the Court from 1993 until her passing in 2020, becoming a prominent figure for her advocacy of gender equality and civil rights. If you're specifically asking about a justice who retired at 82, that would be Justice John Paul Stevens, who retired in 2010 after 35 years of service.
