When we work on the Internet at a computer, we forget about our health. A sedentary lifestyle and constant focusing on the monitor causes great damage to our health. I recommend cycling, and daily cycling for 1-2 hours a day. 1. Blood circulation, lymph, on the third day you will be surprised at how the metabolism in the body normalizes. 2. Vision. When you ride a bike, even at low speed, your eyes involuntarily focus on different objects. Thus, there is a charge for vision.
