A member asked:

When i run a lot i breathe really fast and hard, but when i try to slow it down i feel my throat start closing, vision turns black and get dizzy, why?

Running: I do not know what you mean by running a lot, but if you are not in condition and exceed your limits this can happen. It would be best to get into a training program and maintain your level and increase it as tolerated. You should also see your family doctor to make sure your health allows you to do this.
