You may have more stress than you think. I speak from experience. I have always thought of myself as a calm guy and others that know me will sometimes comment on how I am able to stay so calm. So I was the last person to think I was stressed.
Things we take for granted, that we don't think will give us stress, like getting stuck in trafic, family members getting sick, making the mortgage payment. And the list goes on and on.
I can tell you that since I have been doing SR I have reached a whole new level of calmness. What a boost to the immune system and overall health. I have been able to put myself in the " Zone " easly. I can even do it sitting here at the computer.
I too am a health gaget person. I have spent many dollars for health products. Some good, but most a waste of money. You should look into this, I think you would like it and find it is another step to wellness.
