 2. Low blood pressure is the best insurance you can buy.

Recently a cardiologist told me one of the above after measuring my blood pressure, ECG, etc. I am sorry to say that I don't recall whether he used the first sentence or the second sentence.

My blood pressure was 125/80. It is low and excellent according to him. I am training 3 times a week at the gym. This is the reason for me to maintain the blood pressure like a man of 25 years age. When you are 25, you blood pressure hovering at 125/80.

My question is whether to write 'The blood pressure' or 'blood pressure' in this context.

I know an article is not correct when it comes to uncountable words. However, when we want to generalize, we write an article. Your blood pressure is throughly countable. No doubt about it! There is a limit for the both values. So it should be 'The blood pressure'. On the other hand, this is a general statement a by a cardiologist to a patient. Thus, you could skip the article too. I am not sure.

Should it be 'The blood pressure' or 'blood pressure'?

Hi,

1.The low blood pressure is the best insurance you can buy No

 2. Low blood pressure is the best insurance you can buy. Yes

I know an article is not correct when it comes to uncountable words. However, when we want to generalize, we write an article. <<<No, on the contrary, you don't use an article to generalize. Consider the general statement, 'Sugar is a sweet substance'.

Your blood pressure is throughly countable. No doubt about it! No, it is measurable (125/80) , but that is not the same as being countable. It's like 'My speed is 100kph'.  There is a limit for the both values. So it should be 'The blood pressure'. On the other hand, this is a general statement a by a cardiologist to a patient. Thus, you could skip the article too. I am not sure.

Should it be 'The blood pressure' or 'blood pressure'? To generalize, omit 'the'. But say 'the' in specific statements like 'the blood pressure of a man of 25'.

Blood pressure  is a term that can be treated as countable or uncountable, but in this context it is uncountable.

This is the reason for me to maintain the blood pressure like a man of 25 years age.

The above is not correct and it should be the following:

 
This is the reason for me to maintain the blood pressure like a man of 25.

What is wrong with to say 'a man of 25 years of age'?

 Clive says countable is not same as measureble. Of course the two are different.

I thought a measaurable item would naturally qualify as an countable.

It is not the case. I don't dispute what Clive telle me here; Clive knows better than me. 

So the following are correct. If I am wrong please tell me because this is a mistake I have been making for years. 

He is a man of 25.

He is a man of 25 years old.

He is a 25 year old man.

If I ask someone's age, the answer is:

I am 25.

I am 95.

Is it incorrect to say the above? Please tell me.

Usually people don't say I am 25/95 years old.

 A car, a table, a computer, etc are fine because they are tangible as well as countable items.

I can't understand how it is correct.
