Hi John, It's not that difficult; your body increases the blood pressure when you are: scared, afraid, excited, in love, doing sports, etc... and the body lowers the blood pressure when you are resting physically and/or mentally, during activities such as sleep and meditation. A high blood pressure is good for moments that you really need the oxygen & energy, like with sports, but not for a long time .. Because the veins in your body can handle the pressure but not for a long time ...so if you have a high blood pressure for a long time, these veins can bursts open, which can result in an infarct of an organ (e.g. heart, brains, liver etc.). On the other side you have low blood pressure, which is very handy for preserving your energy, but it can be very dangerous too ...this is because your blood is the transport mechanism of the body, which delivers "all the things needed" to all the organs. If the blood pressure is too low .. your organs (especially your brain) can't get enough fuel or air. for example some people faint when their blood pressure is low. I hope you're project will work Greetings Dave
