1) Brain Freeze!
Who hasn’t eaten ice cream so fast that they have felt an attack of painful cold in their sinuses? The scientific term for this, loving known as brain freeze, is “sphenopalatine ganglioneuralgia.”
2) The Air That I Breathe
When your heart stops, it can be restarted by defibrillators or CPR, but the sooner it is beating again the better. If the brain is deprived of oxygen for just 5-10 minutes, which is delivered by the blood that heart pumps, permanent damage to the brain will occur.
