Sports watches are all the rage at the moment. These gadgets not only tell the time, they can also help you monitor your pulse. But what exactly is a normal heart rate?
Your heart rate is one of the easiest ways to analyze your health. The average person, when not engaged in exercise, should have a heart beat of approximately 60 to 100 beats per minute (bpm). If it is lower than this, the heart is beating too slowly and, even though a slightly slow heart rate is not overly problematic, if it goes below 40 bpm, this is indicative of an issue with a person’s cardiac conduction system.
On the other hand, if the heart rate is in excess of 100 bpm, one might have a sense of a rapid heart beat in the chest. It often happens that if you skip breakfast, the heart will start to beat especially fast as blood sugar levels have dipped too far by lunchtime. If, however, the heart is beating at more than 150 bpm, this really is too fast, and it could well mean cardiac arrhythmia, or even problems with the thyroid gland. If this does happen, you should seek medical attention, regardless of your normal heart rate.

時下流行的運動手環，不僅能看時間，還有監控心跳的功能，但究竟每分鐘心跳幾下才算正常？
最簡單的判讀就從心跳開始，正常人在沒有運動的情況下，心跳每分鐘約為六十到一百下，若低於六十則為心跳過緩，稍微過慢問題不大，但要是低於四十下，則代表心臟傳導系統出了問題。

另一方面，若是心跳超過一百下，就會感到心臟在胸口「砰砰砰」用力跳動的感覺，通常沒吃早餐，到了中午血糖過低就容易心跳特別快，但如果高於一百五十下，就真的太快，可能代表心律不整甚至是甲狀腺出問題，建議不論太高太低都要就醫。

Cardiac arrhythmia — or irregular heartbeat — affects millions of people, and is caused by problems with the cardiac conduction system. When the heart rate is too fast, it is known as tachycardia; when too slow, it is called bradycardia. While it may occur at any age, it is more common among older people.
While most types are not serious, some can predispose people to stroke or heart failure. The good news is that most types can be effectively treated.
Historians are rethinking the way the Holocaust is being presented in museums as the world marks the 80th anniversary of the liberation of the last Nazi concentration camps this month. Shocking images of the mass killings of Jews were “used massively at the end of World War II to show the violence of the Nazis,” historian Tal Bruttmann, a specialist on the Holocaust, told AFP. But in doing so “we kind of lost sight of the fact that is not normal to show” such graphic scenes of mass murder, of people being humiliated and dehumanized, he said. Up to this
When people listen to music today, they typically use streaming services like YouTube or Spotify. However, traditional formats like vinyl records have regained popularity in recent times. Vinyl records are circular discs that store music in grooves on their surfaces and are played on a turntable. As the turntable’s needle runs along these grooves, it picks up vibrations and translates them into sound. The history of vinyl records dates back to the late 1800s, but material and technological challenges delayed mass production until the 1950s. Despite early versions having short playtimes and poor sound quality, vinyl records introduced a new era
