If you're keeping a bucket list, consider this: Nobel Peace Prize winners are, on average, 62 years old when they win the award.
There have been outliers since the prize was established in 1901 — the oldest winner was 87; the youngest, 32. But in general, laureates are old enough to have accomplished some long-term goals but still young enough to check off several more.
The Grinnell Prize is more impatient. It recognizes people who trigger positive social change through "creativity, commitment and extraordinary accomplishment" before their 40th birthday. Every year, three winners each receive $100,000 — half to the individuals themselves and half to their respective organizations.
