If you have high blood pressure, cut out coffee.
When I go to the Doc I refrain from having coffee since just putting a blood pressure cuff on me at a Docs office raises my pulse and blood pressure.
Coffee is known to raise BP by 5 points.
Also, makes it harder (vein wise) in blood tests, I hear.
My blood pressure never goes much over 100/70, my resting heart rate is about 30...with coffee. Big guy in good health.
BTW, Zenjitsu: Fuhuquan/EPKenpo here ;)
