- A person cannot taste food unless it is mixed with saliva. For example, if strong-tasting substance like salt is placed on a dry tongue, the taste buds will not be able to taste it.

- If you spell out consecutive numbers, you have to go up to one thousand until you would find the letter "a"
- The US Interstate road system was designed so that one mile in every five must be straight. These straight sections are usable as airstrips in times of war or other emergencies.
