To say "over-exercise", I don't mean 45 minutes running on treadmill and followed by 10 weight lifting. No, I mean a few minutes more walking (my average time of daily walking is about 25 - 30 minutes, even less). My body, especially my heart, seemed to be pushed a little hard by my previous biking and walking improvement. So I had to slow down a little. Even though I knew this piece of puzzle long time ago, I had not really learned the right control. I walked or biked a little as long as I felt I could. However, this time I canceled these activities completely for a short period of time. And it worked! It was exactly what my heart needed!
For several months (that is from November to January), I started feeling incredibly easy on my daily life. I am able to handle all routine tasks and even some extra energy to enjoy myself. Yes, I still have some symptoms, but those are no more "fatal" ones like my heart and breath problems, which knocked me down totally. I realized this means that my body energy storage increase. And my careful diet certainly was the hero of this achievement!
This year is "Snake" by Chinese zodiac calender, I am snake. In my previous Snake year (12 years ago) I got my green card approved, this time, I hope my health will get some fundamental change, which will serve as "green card" for my new life.
I've already seen the light!
