The normal heart rate for a person ranges from 60 to 100 beats per minute, and less than 60 is considered a reaction accompanied by dizziness and weakness, while more than 100 is a feeling of palpitations and shortness of breath.

I actually don't know either, but since I became a market analyst, I have to discuss a bit even though I don't understand, just like bloggers, they basically do live broadcasts without any requirements, I can understand talking about technology, but they talk about all aspects of life, even about the color of their widow neighbor's underwear, they teach others daily, is that annoying? You see, I have never taught anyone, I usually just mess around and mock, I don't teach anything I don't understand.
The success in the long trade is up to you, and I have no connection to it, and I will not tell you any platform to make profits, as this is not within the scope of my criticisms.
Continue talking about the heart rate issue, three levels, it seems they can fit different levels of demands, if you are playing at the four-hour level, just endure the shortness of breath! Play with me! When these demands reach 3650, I guarantee you that when you cook with your girlfriend, your heart will not race.
