  1. 1 to 2 seconds ✔
  2. 5 to 6 seconds
  3. 10 to 12 seconds

Why: Press a thumb on the gum and let go. The pale spot should turn pink again in 1 to 2 seconds. Slower refill, or dry, dark or pale gums, can mean dehydration or shock.

Huh, didn't know that: Healthy gums are pink and moist, so checking them is a quick, free health check anyone can learn.
