Technology is more contagious compared to the most contagious disease in the world. This is because everything nowadays is being technologized. One example would be this modern-day candle. It works on batteries (rechargeable via USB), it lights up with a candle effect, it has millions of color options to choose from and it is controlled by an app.
To turn off this “candle”, all you have to do is blow the bulb inside of it and it will be turned off. Just like a real candle.
