Ruth Bader Ginsburg

Called “The Notorious R.B.G.” by fans, the Supreme Court justice, 83, has survived both colon cancer (in 1999), during which she did not miss a day on the bench for treatment, and pancreatic cancer, which was caught uncharacteristically early in 2009, before it spread—likely why she’s lived so long after a bout with one of the most lethal cancers. Amid her cancer trials, she began working out with a trainer to regain her strength. Vogue just reported that she still does an hour-long, twice-weekly workout that involves 20 pushups!
