Smiling is infectious, you catch it like the flu,
When someone smiled at me today, I started smiling too.
I passed around the corner and someone saw my grin.
When he smiled I realized I’d passed it on to him.
I thought about that smile, then I realized it was worth it.
A single smile, just like mine could travel around the earth.
So, if you feel a smile begin, don’t leave it undetected.
Let’s start an epidemic quickly, and get the world infected!
What an amazing poem!!! Written by Jez Alborough first published in his book titled Shake Before Opening.. 
Folks, did you know what else is highly contagious apart from viruses and diseases like COVID-19? Your emotions and your moods, your pessimism and your despair, your joy and your enthusiasm, your anger and your smiles – thanks to mirror neurons all highly contagious!!! Yes, you heard it right- a smile is contagious!! Have you ever noticed when you smile at someone, they smile back at you?
When was the last time you made someone smile? Making someone smile not only makes the other person feel good, but it also makes you feel good too! Think about how great it would feel if you were the reason someone – a different person each day – smiled every single day. Wouldn’t that be amazing? Imagine if everyone strived to make at least one other person smile every day. Just think about how happy the world would be!
Smiling is one of the simplest yet most powerful things you can do to brighten your day and the days of those around you. A single smile can lift your mood, reduce stress, lower blood pressure, boost your immune system, relieve pain (by releasing endorphins, the body’s natural painkillers) etc.
Now why it’s Important to Make Others Smile. Everyone has bad days. Sometimes, all someone needs is a smile from someone else to turn their day around. You’ve probably experienced a similar situation before. You’re tired, grumpy, and feeling like the world is against you, but then someone does something nice for you or even smiles at you, and suddenly your day doesn’t seem so bad anymore. By making an effort to put a smile on somebody else’s face, you may find that you’re able to make your day a little bit better. It’s a win-win for everyone involved.
As Roy T. Bennett says: “Be the reason someone smiles. Be the reason someone feels loved and believes in the goodness in people.” You can be the reason every day. Why not start today?
