Each day your heart beats 100,000 times and your blood travels 60,000 miles. Without even lifting a finger!

Ever wondered how you continue to vomit on an empty stomach? Each day, the body produces 2-3L of gastric juice & 0.5-1.5L of saliva.

Cigarette smoke contains carbon monoxide, which impersonates oxygen in the body but cannot be used for cell respiration & energy production.

Pets can relieve stress! Owning a pet has been shown to reduce blood pressure and plasma renin levels (stress hormone). So stroke away.
