Mine, being 37, is 183. Again, more or less. And then you want to be around 70 percent of it. 65 percent to 75 percent of it for moderate effective benefit of exercise. And to keep in mind that the quantity does affect quality. And once again we have the graph that we see so often: the curve linear relationship. So if on this side of the graph, we had psychological plus physiological benefit, and here we have effort or amount of work, the graph looks like this, where too little effort is not good. We are compromising on our base level of happiness. Too much effort is also not good. That's when we experience the staleness and the anxiety. And what we want to get to is more or less around our optimum level. And also optimum level given how much time we have. Yeah, in an ideal world, I would work out six times a week for one hour each time.
