Came out older than my real age - I went 'back' to see what could have accounted for this, since I ticked 'no' for all the bad stuff and have a low BMI. The only thing I could see that could possibly account for it is that I put 'don't know' for my cholesterol and blood pressure - so I was then badgered about doing something about my cholesterol and blood pressure.
Ok, here's what I don't get. Because I said 'don't know', the survey said it would use 'average' figures. So, my score is 'better than average' for almost everything (no 'bad stuff', BMI excellent); they've added on two 'average' guesstimates, and I've ended up significantly worse than average. I don't know much about heart health, but I have a vague understanding of how numbers work, and I struggle to see how that makes sense.
