Private Property Is Exempt. The First Amendment usually applies only to public property, but there are gray areas. You can gather on your own property, but not on your neighbor's lawn against your neighbor's wishes. The individual who owns the property has the right to say what can and cannot happen there.
The human body is sensitive to caffeine. It increases mental awareness and helps you stay awake longer. The substance is present in soda, tea, coffee, sports beverages, chocolate and certain medications. After you consume caffeine, the substance enters the bloodstream within minutes and affects your brain.
Under resting conditions, caffeine has been shown to cause increases in blood pressure (25, 27, 38) and systemic vascular resistance (6, 38). Moreover, it can provoke elevations in plasma renin activity (5, 27,39, 41) and presumably in plasma ANG II concentrations.
