"Gunk" removal

If you have gunk on a knife (for example, adhesive residue on a swiss army blade from opening multiple boxes), WD-40 will remove it easily.

Best "insurance plan"

The best way to keep your car in working order is to consistently replace your cars oil. Running low on oil severely damages the engine.

Floating adrift

If you find yourself floating lost at sea and a rescue helicopter passes by, use your arms to splash around as opposed to waving your arms and shouting for help- splashes are much more visible to a pilot in the air.

Child protection

Do not put a child's name on the back of their backpack. Child predators could use that information to call out to the child, pretend to know them and gain their trust, and possibly abduct them.

Ceiling fans

Ceiling fans don't cool you by circulating the air- they cool by pushing air over you. They do no good "on" if no one is in the room.

Precautions for closing a bank account

If you decide to close your bank account be sure that you have no pending debit/credit transactions to your account. If you close your account and withdraw all your money and the transactions go through afterwards, you'll end up having to pay an overdrawn account fee.

Super Paper Clips

These are called "binder clips."

Well drinks

A "well drink" is a mixed drink that uses a bottom-tier quality, cheaper alcohol in its creation, as opposed to a "top shelf" drink which uses a more expensive and better quality brand.

Jewelry Certificate

When buying jewelry, particularly those with stones or specific metals, in a foreign country or a non-known store, be sure to ask for a certificate of authenticity with the purchase. If they cannot or will not provide the certificate, don't buy the jewelry.

Certification prevents scamming.

Commuting Safeguard

When using a pass that allows for commuting in a crowded city (ie, a bus pass in Chicago) that requires being pulled from the pocket often, do not store it in a wallet. Otherwise, repeatedly pulling your wallet out may make you a target for muggers and make you a victim of crime.
