1. A newborn today can expect to live a full generation longer than his or her great-grandparents.
Life expectancy has jumped 50% in 60 years!
2. Also, you're younger than you think. Since your cells are always rebuilding, most of your body is only 7 to 10 years old.
Just think — for a brief time, you were the youngest thing in the entire universe!
3. Sea otters hold hands while they sleep so they don't drift away from each other.

The little guys also keep a favorite rock in a pouch on their chest.
4. Listening to music may make you healthier AND smarter.
Just as we thought: a rapid tempo and major key really do elicit happiness.
5. People have made ice cream using 3D printers: DELICIOUS SOFT-SERVE VANILLA ICE CREAM.
3D printers just might end world hunger in the long run.
6. No really, you have a lot of potential in you — your body contains seven quintillion joules of potential energy.
That's like 30 hydrogen bombs, BTW.
7. The happiest animal in the world is the quokka — an Australian marsupial with a perpetual smile on its face.

No clue why he's so happy, but we do know that smiling makes us happier.
8. Humans laugh before they know how to speak — it's a truly universal form of communication!
And yes, it really is contagious.
9. Each year, the Netherlands sends 20,000 tulip bulbs to Canada to thank them for their aid in WW2.
10. The act of hugging releases oxytocin — which lowers our stress and blood pressure.
Even better, though: cuddling.
11. Squirrels forget about three-fourths of the nuts they bury, leading to new trees sprouting in their place each year.
Adult squirrels will also adopt and care for abandoned young. Awww.
12. Contrary to popular belief, it's human nature to be generous. Our brains light up when we're charitable to each other!
Neurologically speaking, helping those in need feels like winning the lottery.
13. Finally, the odds of all your ancestors coming together to ultimately form you — exactly as you are — are 1 in 10^2,685,000.
FYI: That's a 10 with almost 2.7 million zeroes after it.
