Go Ask Your Father: Fat Lips, Vision, AEDs, and Undertows

Happy Thursday night or whatever time of the week it happens to be for you when you’re reading this. I’m settling in getting ready for yet another snow storm. School was cancelled Monday because of snow. It was cancelled Wednesday because of ice. It’s likely the kids will be home to drive me nuts again tomorrow because of more snow and ice. I’m putting them work if they’re home tomorrow!

Why do we get fat lips?

You can tell a lot about a person by looking at their lips. You can tell if they’re wearing lipstick, for instance. You tell how big their labial tubercle (that bump in the middle of the upper lip) is. And women, did you know the bigger your labial tubercle the easier it is for you to achieve orgasm? You can also tell if they’ve been in a fight. When the soft tissue of the lips is damaged it becomes inflamed and swollen. This creates what we all know as a fat lip. Bet you never look at lips the same way again.

Beside getting a taste of a knuckle sandwich, fat lips can also be caused by dehydration, an allergic reaction, from a food allergy, or sunburn.

How do eye glasses work?

DW and I are nearsighted (myopia). She wears her glasses all the time. I have a tendency to lose mine. One pair is at the bottom of a river. Being farsighted simply means that our eyes do not have adequate focusing power. In other words, the focus point falls behind the retina instead of on it. Farsightedness (hyperopia) is exactly opposite – it forms a focus point in front of the retina. So eye glasses and contact lenses redirect the light so that it focuses the image on your retina so you see a clear picture.

The top image shows how light focuses on the retina.

What’s an AED?

While ice skating yesterday, Bang noticed an odd looking box attached the wall outside of the ice rink. Naturally curious he wanted to know what it was. It was an AED or Automated External Defibrillator. Automated because all a user needs to do is follow audio commands connect adhesive electrodes to the patient and from there the computer takes over to check for a pulse and heart rhythm. It will only deliver a shock if it detects a heart that is in ventricular fibrillation (Vfib), when the heart beats with rapid, erratic electrical impulses. This causes pumping chambers in your heart (the ventricles) to quiver uselessly, instead of pumping blood. The shock momentarily stuns the heart and gives it the chance to resume beating effectively. Essentially, it turns it off and turns it back on it again to restart it.

What’s an undertow?

Not to be confused with rip currents, an undertow occurs in all bodies of water where waves crash on shore. It’s strongest in surf zones where the waves are larger. After the wave rolls onto shore gravity pulls back toward the ocean and the water rushes back out collecting in the next wave. This outward rush of water and the inward rush of a wave creates an undertow. They are only dangerous to those who can’t stand against the backwash (outward rush of water) like children as the undertow only goes out to next incoming wave.
