Having trouble hearing someone at a party or on the phone? Use your right ear it’s better at picking up rapid speech. But, the left is better at picking up music tones.

3. Cough while injection

Next time the doctor’s going to give you an injection, cough as the needle is going in. The cough raises the level of pressure in your spinal canal, which limits the pain sensation as it tries to travel to your brain.

If you get all messed up on liquor, and the room starts spinning, put your hand on something stable.

You can prevent brain freeze by pressing your tongue flat against the roof of your mouth, covering as much surface area as possible.

By warming up the roof of your mouth, you’ll chill your brain and feel better.

11. Waking up a sleeping hand

If your hand falls asleep, rock your head from side to side. That’ll wake your hand or arm up in less than a minute.
