Grandparents have always been important. Today, they're even more important. In busy, two-career and single-parent families, an involved grandparent goes a long way to filling a void for children. In extreme situations, the courts have found it's often a grandparent who can reach a troubled teen when no one else can.
Some people, genetically, are born with weaker or smaller veins than others - and some people are born with larger, and more flexible vein tissues. Due to genetics, some people just have poor, weak veins. This only affects the large return veins you can see however - the veins which transport the rest of your blood are likely fine. Regardless of the vein size, blood can still be drawn. I personally have smaller and weaker veins, and can still donate, but sometimes it takes a few tries.
For most people, it is a cosmetic issue, but for some people varicose veins may cause pain. In some cases serious complications, such as phlebitis (inflammation of the veins), skin ulcers, and blood clots, can happen. Veins move blood from your body to your heart. When the one-way valves in your veins get weak, they may allow blood to flow backward and pool in your veins. That causes your veins to get bigger. Varicose veins usually show up in the legs and feet, because standing and walking increases the pressure on these veins.
