Since I caught a cold, I have started to exercise according to the doctor's instructions. In the past month, my mind has changed a lot.

The melancholy and vicissitudes of life in the past began to become young and positive. So I have not only a guess.

Is this feeling of melancholy vicissitudes formed in the face of heavy rain and ice and snow detention in primitive life?

Our ancestors watched the storm and snowstorm and couldn't move a step. They have to endure cold, hunger, idleness and worry about their wives and children. After all, you can eat less Doce and save money. Less activity can save energy.

So you should be sad if you are not sad, and you should be sad if you are not sad. In our blood, there are melancholy genes written by our primitive ancestors.

Now, I am in a similar situation to my ancestors. Locked in a small house, I hurried back to my small house after work. I found that melancholy feeling again.

Therefore, after starting fitness, my mind gradually became cheerful and my personality became positive. Of course, this is all the result of running in the suburbs. If you get a card to go to the gym, I'm afraid it will be even more heartbreaking because of the contradiction between sensory detention and physical freedom. Ha ha!
