Thankyou for the information,
Its good to hear that you do not drink alcohol and niether you smoke.The smoking, obesity is a risk factor for heart disease.
The blood pressure of 140/80 is not very high as the range for systolic blood pressure is 120 to 140 mm Hg.You need not worry as you are still in the high normal range,.
The slight increase in blood pressure can be there as the age advances due to loss of elasticity of arteries.
You just need to follow a few precautions so that you remain healthy.You should take less of sodium salt and oil in the diet and try to be stress free.The cutting off some extra weight and daily exercise will make you more fit.
