1. A hiccup (medical term, Synchronous Diaphragmatic Flutter, or SDF) is an involuntary action involving a reflex arc that leads to the contraction of the diaphragm several times a minute. In humans, the abrupt rush of air into the lungs causes the epiglottis to close, creating a "hic" sound. Hiccups often occur after consuming carbonated beverages, alcohol, or spicy foods. Prolonged laughter is also known to cause hiccups.
2. On May 28, 1959 two monkeys were successfully sent to space and recovered back on earth aboard Jupiter MRBM AM-18. American-born rhesus monkey "Able," and South American squirrel monkey "Baker," rode to the altitude of 59 miles. Although not the first monkeys to make it to space, they were the first ever to survive the trip home and land alive.
