hey mate, i dont know u or ur old man but good to hear hes doing well =)
My old man has been very weary with his health for a long time & he know his family history of having heart problems.
He took the initiative to actually have a check up every 6 months for cholesterol & blood pressure & to exercise 2-3 times a week. He actually loss weight hes around 72kg now & am 5 kg heavier lol fark, anyways hes been doing this routine for 2.5 yrs now & my mom has been tagging along with him for an afternoon walk around the block. They also changed their diet too. It made me realised how important a routine check up can make a difference, to prevent heart problems or any other diseases, to treat it early before it gets worst. =)
