Know Your Numbers! Week 2015 runs from 14-20 September. The campaign, run by charity Blood Pressure UK, is in its 14th year and this year is aiming to highlight that in the time it takes to boil a kettle, people could have taken a blood pressure reading which might save their life.

Some 16m people in the UK suffer from high blood pressure. The picture is the interior surface of a human eye affected by hypertensive retinopathy, showing haemorrhages (dark patches) and cotton wool spots (light patches). Hypertensive retinopathy is damage to the retina caused by high blood pressure.
