In order to take good care of your health, you should have a full medical examination at least once a year. However, you should also watch out for your health between doctor visits. There are special tests that you can do in order to diagnose a serious illness, even before the first symptoms appear.

Make your fingers in the shape of an upside down letter J and put your nails against one another. Do you see a tiny diamond between them? Great, this means that your heart and vessels are perfectly healthy.
If there is no space between your fingernails, it may be a sign of nail clubbing. The fact that fingers become thicker means that the blood doesn’t have enough oxygen. Oxygen deficiency can be caused by multiple reasons. For example, cardiovascular diseases, lung problems, and gastrointestinal issues.
