The reason paper cuts are so painful is that you usually get them on your fingers and
finger tips. Finger tips and hands have significantly more nociceptors (nerve fibers)

People who laugh a lot are much healthier than those who don't. Dr. Lee Berk at the Loma
Linda School of Public Health in California found that laughing lowers levels of stress
hormones, and strengthens the immune system. Six-year-olds have it best - they laugh an
average of 300 times a day. Adults only laugh 15 to 100 times a day.
You are taller in the morning than in the evening.
When you get out of bed in the morning you are at your tallest. On average, you are
approximately one half inch taller when you wake in the morning, thanks to excess fluid
between and within your spinal discs. While you are sleeping, these fluids replenish. During
the day your body has to deal with the stress of standing, so the discs become compressed
and the fluid seeps out. This results in your losing a small amount of extra height.
