Can I Safely Do Push-ups With High Blood Pressure, Especially Since I Can Do More Than 40 Despite Previous Alcohol Consumption?

Hi I wanna understand more about high blood pressure and push ups...all I know that push up is good for the heart and I don t know if they are mistaken about me that I have a high blood pressure because I use to drink 4 -5 cans of beer from the 2 previous years, They said that If you have high blood pressure you can not do push ups more than 10m but I can do more that 40 ..
