Heart disease is a big problem in Britain, causing an average of 460 deaths per day, according to the British Heart Foundation. The organisation says that heart and circulatory diseases cause a quarter of all deaths in the UK - more than 160,000 every year.
It is caused by the blood supply being blocked or slowed down by fatty tissues building up in a person's arteries. With that in mind, it's worth being aware of the tell-tale signs of any problems, including having sock marks on your ankles, reports the Mirror.
This is evident when there is water retention in the feet and legs, known medically as peripheral oedema. When you take your socks off, you might see a distinctive line across your ankles from where your socks were.
