Yes, you can't argue with a professional cardiologist.
While girls discuss flowers, candy, gifts, and "did he text me or didn't he," as a cardiologist, I view February 14th purely from a scientific perspective. It's a day of increased stress on the country's cardiovascular system.
First, a rapid pulse.
He invited me to dinner, sinus tachycardia.
She said, "We need to talk," a near-infarction state.

Second, blood pressure spikes.
A marriage proposal causes an immediate increase in systolic blood pressure.
Flower prices on February 14th raise blood pressure even higher.

Third, arrhythmia.
The message "Why were you in the chat and didn't text me?" guarantees extrasystole.

Sometimes I think Cupid is my freelance assistant. He shoots, and then I explain to patients that the butterflies in their stomach have nothing to do with their stomach, and the phrase "heart jumping out of my chest" is just a metaphor, so breathe calmly and evenly.
Seriously speaking, falling in love really does affect the heart. Adrenaline and dopamine levels rise, the pulse quickens, and blood vessels dilate. Love is officially certified cardio exercise, and it doesn't require a gym membership.
So on February 14th, I accept congratulations, candy in reasonable quantities, and thanks for saving hearts, both literally and figuratively.
The best gift for a cardiologist on Valentine's Day is for your heart to beat faster from love alone, not from cholesterol.
Take care of your heart. And if you're going to lose your head, do it with a normal pulse. 💓
