How to tan safely
Cover your eyes with goggles.
Goggles are provided in tanning beds for a reason. You need to protect your eyes from the rays you're exposing your body to, and the goggles will provide that protection.

They should fit snugly over your eyes. Make sure you use goggles specifically designed for tanning beds or lamps.

How to measure mm
Look at the unmarked lines on a metric ruler.
The numbered lines represent centimeters, but the unmarked lines represent millimeters.
If a metric ruler is too small, you could also use a meter stick.

The small, unnumbered lines on a meter stick that fall in between the numbered lines should still be millimeters. Note that each 1 cm also equals 10 mm.

How to ski moguls
Use stiff skis with flexible tips.
Stiff skis have a large turning radius and they will help you brake and slow down. The flexible tips aid you in maneuvering around each of the moguls with ease!
Shorter skis will allow you to make tighter turns, but will help out less when you try to slow down.
Keep your upper body upright and your arms out in front of you. The majority of your body motion will come from keeping your legs relaxed as you ride over each bump.
