Blood

I can see your blood And all the paths it takes How fast or slow I takes If it's bunching up in your neck It is a stroke you can expect When it's filling the paths hard and strong High blood pressure is what's wrong If you come from an exercise class I see it flowing very fast If it's moving fast I'm not clear But usually I find it's because of fear Sometimes I see things that don't belong there Usually those people are somehow impaired The bloods sometimes slow, In people that are old. I see blood, sometimes good Sometimes bad And that is the very super power I have
