"A healthy BMI - a calculation of weight to height - for adults is 18.5 to 25."


BMI is not an accurate indication of whether someone is overweight. I spent 20 years weight-training and although I haven't done it for around 12 years still have a BMI in the 'overweight' category (27.1) despite having a waist measurement of 33 inches and very little body fat. Some of the bodybuilders I used to train with would have had a BMI off the scale.

My ex-father-in-law, who died a few weeks ago at the age of 96, was refused a hip replacement the age of 75 on the grounds that he exercised with weights and a exercise bike every day and so was considered too active.
