Have you ever looked down at the veins on the back of your hands and wondered what they say about your health? Well, you're not alone. A lot of older folks believe that big, bulging hand veins mean you’re strong and healthy. Some even say it’s a sign you’ll live a long life. This idea comes from traditional Chinese medicine, which talks about “vitality in the veins.” But in reality, visible veins don’t always equal good health.
