Dr. Faisal Zawawi, an Otolaryngologist and member of the McGill Auditory Sciences Laboratory, notes that when a person is exposed to loud noises it can cause short-term hearing loss but that under normal circumstances the body typically is able to repair the loss of hearing within 72 hours. However, Zawawi warns that if symptoms are not reversed (倒转) in the first 72 hours the damage could become permanent. Due to findings in previous studies about it, Zawawi says that the team of researchers has suspected that something may stop this repair process; therefore, the team set out to determine if caffeine could be a contributing cause to hearing loss. According to the Medical Daily, the researchers tested what they suspected on female guinea pigs(FGP) (豚鼠).
To perform the test, 24 female guinea pigs were split into three equal groups with each group exposed in different levels to caffeine, and loud noises. The researchers found that the guinea pigs subjected to only sound had their full hearing recovered by day eight. However, the guinea pigs that were subjected to both caffeine and loud noise never fully regained their hearing. Therefore，the researchers concluded that caffeine is a likely contributing cause to permanent hearing loss.
“This research confirms that while a cup of coffee may seem appealing after a long night at a loud concert, drinking caffeine produces more of a risk than benefit when it comes to a person's hearing. Although further research is required to understand the effect on humans, the results are promising," says Zawawi. If the research proves successful, the removal of caffeine from your diet following noise exposure could prevent permanent hearing loss as the body will be more able to repair itself naturally.

Many of my summer, childhood adventures were related to that classic American experience of the family road trip.
We visited Carlsbad Caverns when we took a trip out west so my father could look for work. A concrete tent called “tepee” by American Indians, which we spent the night in, has stuck in my mind. This was at Wigwam Village Motel in Holbrook, Arizona, on Route 66. The city was founded in 188 l, when the railroad was built, and named to honor the first chief engineer of the Atlantic and Pacific Railroad. I slept on an army type bed just below the attractive air conditioner.
Another time, our family took our summer vacation at a small wooden house that belonged to one of my father 's friends for a couple of years in the Adirondacks. We had to take everything we needed up a steep hill to the house that you couldn't see from the road that passed in front of it. There was no mailbox and the only indication that there might be something there was a small courtyard where you could park a car. We had packed all the food and clothing we would need for one week. After all, it wasn't like there was a Walmart nearby.
The week's entertainment consisted of catching insects and snakes and playing in the small lake that was across the road from the house. I have never seen water as pristine (清澈) since. I would catch small fish by hand and set them free. Seven days passed before I knew it!
These trips are our family's history. We were making our, own history and placing the historical markers of our lives along the road.
