After an elderly man rescued a drowning 8-year-old, he realized something incredible.

There’s a family in Jiangsu province, China that owes its compete existence to an 80-year-old-man named Xu Weifang.

An eight-year-old boy was playing with his grandmother beside the river near Xu’s home. The boy accidentally slipped and fell into the water and didn’t know how to swim.

Xu and his wife heard the boy's screams, ran out to see what was wrong and saw him struggling to keep his head above water.

Xu was still recovering from injuries he sustained after a fall two years ago, but without hesitation, he lowered himself into the river and pulled the boy to safety.

The boy was later taken to a hospital.

This wasn’t the first time Xu had saved a member of the boy’s family. Thirty years ago, he saved his father from drowning in the same river.

“When I was younger, her son [the boy’s father] was drowning in the river and I jumped to save him,” Xu recalled. “Now that I’m old, I can’t jump anymore.”

Over the years, Xu and his wife have rescued four other people from drowning in the river.

Now that they’re getting up there in age, maybe it’s time the community started a swim school.

Everyone has heard stories of the strange and intense food cravings women get when pregnant. There's the pregnant woman who had to have dill pickles dipped in ice cream or the one who couldn't make it through the night without a bucket of a specific type of fried chicken.

Researchers have yet to lock down the exact reason why pregnant women have these seemingly unnatural cravings, but there are a few reasons that are often cited. Women who are pregnant experience heightened senses of smell and taste that can have a direct effect on their appetites.

Some researchers believe their bodies may be craving specific nutrients they need for a healthy pregnancy. Others have suggested that dietary requests at odd hours may be a way for a pregnant person to develop a supportive bond with their partner before the baby arrives.
