Unrelated to leap years: my kids can be expected to live through the year 2100 and I think that's just wild! I was born in the eighties, grandparents in or just after the first world war; always felt everyone I know are very 20th century-ish! Not only are we now solidly in the 21st century, thinking that my kids will experience the 22nd century boggles my mind.
