Why did people start making ice pop?

In 1905, an 11-year-old American boy named Frank Epperson accidentally left a glass of soda water and the wooden stick he was using to stir the drink on the front porch. It got cold during the night and the soda froze. The next morning the boy heated the glass under a stream of hot water, took out the contents stuck to the stick, and ate it. This was the first ice pop.

In the 1920s, Epperson obtained a patent and registered the brand name Popsicle, but soon ceded the rights to it to an outside company.

Why do we cry from happiness?

Our autonomic nervous system consists of sympathetic and parasympathetic. One part is responsible for "fighting" and the other for "relaxing" respectively. It's the sympathetic nervous system that kicks in during stress, such as by increasing heart rate. And the parasympathetic system, with its calming function, is directly connected with the lacrimal glands.

When we experience intense happiness, our heart rate increases. And the emotion is so strong that our body cannot recognize it. So our rapid heartbeat activates the parasympathetic system, sending a signal to the lacrimal glands, and we start crying.

That is, the body simply can't tell the difference between a strong positive emotion and a negative one.
