Dangerous level of blood pressure...?

Hello Friends,

Please tell me, What is a dangerous level of blood pressure...?

As U think More than 120 over 80 and less than 140 over 90 (120/80-140/90): You have a normal blood pressure reading but it is a little higher than it should be, and you should try to lower it. many time a congestive heart disease can cause heart failure and death also. So, follow a proper routine and do daily exercises.

thanks for advise...
