1. There's no workout better than your weekly drills.

Nothing like treading water, swimming laps, towing your friends around in the pool, and sometimes even running to keep you in shape.

2. "No running" is a phrase you will yell at children for the rest of your life.

In the park, at the mall, the locations are endless. Old habits die hard.

3. No one is better at counting to 30 than you.

And you're even better at estimating 30 seconds if you forgot to start counting after the last person went.

4. Tan lines are a badge of honor.

No amount of sunscreen could ever keep these bad boys from popping through, but you secretly liked showing them off.

5. Sometimes kids really do pretend to drown.

But you were really good at spotting the fakers.

6. There is nothing worse than jumping in for a kid that wasn't actually drowning.

That game where kids see who can hold their breath the longest is the worst game ever. Better safe than sorry though.

7. You'll never not wear sunglasses outside again.

For one, you probably learned from experience that your eyes can indeed get sun burnt. Also, sunglasses are a necessity for people watching.

8. There's nothing funnier than watching someone trying to get on an intertube in a wave pool.

People forget you're getting paid to stare at them from your stand. You saw people do lots of funny stuff through your Ray Bans.

9. It is actually really important to wear sunscreen on your nose.

Don't ask me why, but no matter how tan the rest of your body gets, your nose will always burn.

10. Public bathrooms are gross. Public bathrooms at the pool are even worse.

Lifeguards are also responsible for cleaning the park, and you saw some things during those shifts. This is probably the only thing you hated about your job.

11. It felt really great when you did your job well.

Not everyone would like to watch a pool filled with 500 people, but you loved making sure every had a safe and fun day at the pool.
