Simple Health Checks You Can Do at Home

The heart and lung disease test

Hold out both your hands in front of you and create a letter J with both (your left hand will make a backwards J. Then lower your pointer fingers to touch one another. Look closely—if you see a tiny diamond shape formed between these two fingers, you have healthy heart and vessels. If they lay flat against each other, you may have nail clubbing, which can indicate cardiovascular diseases, lung problems, and gastrointestinal issues. See a doctor if this is the case.
We want to remind you that self-made tests can’t replace the professional opinion of a doctor. And if you have any symptoms that are worrying you, you should see a doctor immediately.
