I like to sign my books on the title page, which is where most books are autographed, though you can also sign the inside cover. In some cases, you may want to sign the front cover, though this is rare and would probably only be appropriate for a coffee table book or something that will be on display.
High blood pressure can also be linked to overactive nerves in the sympathetic nervous system, which includes the major organs that are responsible for regulating blood pressure: the brain, heart, kidneys and blood vessels.
Blood pressure is influenced by cardiac output, total peripheral resistance and arterial stiffness and varies depending on situation, emotional state, activity, and relative health/disease states. In the short term it is regulated by baroreceptors which act via the brain to influence nervous and endocrine systems.
