The Heart’s Relentless Work

Alright, listen up. That thing in your chest? Yeah,

the heart. Looks romantic, gets blamed for feelings, but trust me — it’s

basically the hardest-working employee in your body, and it never gets a day off.

Every time it beats, it’s pulling off a pretty slick operation. First, it grabs oxygen-poor

blood, sends it to the lungs for a quick refresh — think of it as a pit stop

— and then pumps that oxygen-rich blood straight back out to the rest of your body.

Brain, muscles, even your pinky toe? All getting VIP

service. It does this about a hundred thousand times a day. No coffee.
