The N.H.L. Calling For A Cloudy Forecast

Hockey has been touted as a sport near the top of the totem pole in terms of inherent risk for concussion. You don’t have to look much beyond the fact that the game is played on a sheet of ice to realize why head injuries are so common. Add some body contact into the mix, slapshots that rifle a dense rubber puck over 100 miles an hour, and players with long fiberglass sticks who skate faster than a car drives on a residential street and you have a tragic recipe for head trauma, otherwise known as hockey.

Ever since the dawn of hockey, players have been getting their “bell rung” regardless of whether they are wearing a helmet or not. The game of hockey is an intense test of determination and power and as a result of such ferocity at some point, if you play the game, it is inevitable that you will get injured.  Injuries are an all too familiar part of the game and many are only now realizing that getting your “bell rung”, or in other words receiving a concussion, can have grave consequences.

Despite more information being made accessible to the general public (players included) regarding concussions and their relation to chronic traumatic encephalopathy (CTE), it seems nearly every week another player out with a concussion, some taking longer than others to return. A concussion is noted by the American Association of Neurological Surgeons as being an injury to the brain that results in temporary loss of normal brain function, which is usually caused by a blow to the head. The brain is surrounded by spinal fluid which acts as a barrier between the soft tissue of the brain and the hard bones of the skull. Any jolt or hit to the head can cause rapid movement of the brain in the cranial cavity potentially damaging brain cells and tissue. Concussion symptoms vary depending on the intensity of impact but in general, can last for less than a day or persist for weeks – even months.

Millions or Brain Damage?

To help reduce such head injuries the National Hockey League (NHL) implemented a new concussion protocol two years ago. The new procedures included off-ice education for players regarding concussions as well as mandatory removal of a player from the game for an acute evaluation if he is hit and a concussion is suspected. Contrary to recent amendments, concussion rates are as high as they’ve ever been in the history of the sport, but, despite this, players like Rick Nash are making use of the off- ice education. The six-time All-Star has called it quits at the young age of 34 due to concussion-related symptoms, passing up millions of dollars in hopes of saving his mental health. With almost anyone who laces up the skates, their dream is to make it to the big leagues but many fail to realize that the dream often comes at a price, and there is no amount of money that can reconcile for serious brain damage.

Does time flies?

The clock was invented by human beings to keep track of time. The atomic clock is one of the most accurate clocks in the world,  it will not gain or lose one second in 15 billion years. Therefore, the time will not fly. However, sometimes we do feel that the time pass by quickly when we are having fun. The time seems to crawl when we are having a boring class.

Some people suggest that when we are having fun, we are paying attention to what we are doing. Therefore, we can not notice that the time pass by. However, when we are feeling bored, we will focus on time and notice that the time crawls.

 

Dr. Michael Shadlen said that “Every thought has various horizons”.Time flies according to these horizons. When we are really focusing on doing something, our mind can see the near horizons and the distant horizons. This makes the time goes by fast. In contrast, when we feel bored then we can only notice the near horizons and the horizons are not link to each other. As a result, time crawls.

It can also be related to the cells in the brain. Neuroscientist Joe Paton found out the neurons in our brain will release neurotransmitter dopamine which is a type of chemical that impacts how the brain feels about the time. When we are having fun, the neurons will release much more chemicals than usual. These chemicals make us feels that less time goes by. On the other hand, if we release lesser this type of chemicals, the time will go slowly in our mind.

In conclusion, time does not fly in reality. However, it does fly in our mind when we are having fun.
