We our daughter stayed at home with us, but it is her choice, and she is not a child any longer.

A woman in Pulaski, Virginia, says she was stopped by a squirrel, who pulled on her leg repeatedly and led her to help its injured baby.

Tia Powell was walking in Kiwanis Park when she was "approached by a squirrel", the Pulaski Police Department wrote on Meta. The squirrel stood in her way on the path. After realising that the squirrel did not mean any harm and wasn't going to leave her side, Powell turned around and the squirrel led her down the path to a baby squirrel with an injured leg.

At one point, Powell wasn't sure she could help and she began walking and the squirrel followed her again and actually pulled her trouser leg! So, she fed the squirrels a sandwich she had with her and watched them try to jump up into a tree. When she realised the baby squirrel was still struggling to get up the tree, she decided to call in backup. Powell called the Pulaski Police Department.

Powell didn't know how the baby squirrel got injured, but she thought a nearby street cat was the culprit (肇事者). So, the group of rescuers decided to move the squirrels to a safer area. "We were able to get the baby and mother to a different area with more trees and it was able to climb all the way up and they looked very happy," Powell said.

She went back a few days later to show her kids where it all went down. In the trees, Powell spotted two squirrels staring at her, and couldn't help but wonder if they were the same squirrels she rescued.

. When we meet with something we're not familiar with or something frightening, our brain and body start making changes to help prepare us for the unknown. Dr. Kerr says, "For some people, choosing to be scared can be fun. "

What good is fear?

. It tells a person to hide, run away, or defend oneself. Faster heartbeat and breathing send more blood and oxygen to the muscles so they are ready when they are needed. Stress chemicals can make a person more alert.

Our memories also help protect us. We keep a close eye on babies because they don't understand what might hurt them. As babies grow, they learn what's unsafe, and their brains store those memories. Then their brains use fear to warn them of dangers. "We don't want to be fearless, "Dr. Kerr says. "!"

Too much can be harmful

Experiences can lead to long-lasting fears that may stop a person from trying new things. We're born with the ability to feel fear, but a lot of what we're afraid of is learned.

"Being afraid doesn't mean you're weak," Dr. Kerr says. A long-lasting fear can mean you've had a bad experience, and your brain doesn't want you to have it again. . Other people may have no special fear of dogs but may be afraid of other things, such as heights, snakes, or spiders.

How to feel less afraid

Many people have beat their own fears. Here is one method: Instead of listening to their imagination, they learn the facts about anything that seems scary. .

Dr. Kerr grew up on a farm. As a seven-year-old, she was scared of black bears in the woods. Later, she read about them. "Understanding the facts gave me a sense of confidence, "she says." I knew for sure what to do if I ever met with a bear and how to protect myself."

A. Knowledge can help a person feel less afraid

B. Being scared is not always a bad thing

C. Fear is a tool that the brain uses to keep the body safe

D. That is why our brain works faster in time of danger

E. It is good to have a healthy sense of what's dangerous

F. Some people are scared to death by his own shadow at night

G. If a dog bit someone, that person might feel afraid of all dogs

Thousands of runners gather for the annual Marathon. The largest holiday race in California1 folks of all ages, sizes, shapes, and 2. The gun goes off and runners push for position. I just3 at the new day and feel righteous for having gotten up and down to the event.
