That really depends on your doctor. Some people are high at 140 and others at 130 for the systolic. If you are young, I think 130 is pretty high. If you are older maybe 140 if the point where you should be paying attention.
For the diastolic 80 is good. 85 is take a note book when you go see a doctor and 90 it's time to be a worry wart.
These are just numbers. Throughout the day, the numbers can vary quite a bit so one bad reading does not make you a candidate for high blood pressure.
If you learn to relax before it is taken, it makes a 10 - 15 point difference on the systolic and don't let people bully you about it.

If some guy decides he wants to go on a killing spree, well all I can say is that is Definitely not natural. Hope that helped.
