The Difference between Adults and Children

Here's a picture of pure childhood joy standing on an inflatable in a lake.

Here's a picture that further contextualizes that joy.

Children do not feel cold. Adults, however, do not consider it advisable to get into a lake when the air temperature is 65 degrees F and the breeze is gusting to twenty miles per hour. Instead, adults put on a coat.

Joy comes in many temperature settings.
