Because their veins are more superficial or their skin is thinner.
Watch your weight
As people age, the walls of veins may become less elastic and more rigid due to changes in the structural proteins within the vein walls. This can cause the veins to narrow or become smaller in diameter. Additionally, the accumulation of fatty deposits or plaques within the veins can contribute to their narrowing.
Not really. Some people just have veins that roll no matter what. Your phlebotomy skills will improve with practice.
The blood in the veins is red, but appears to be blue, especially in older people, when seen through the skin.
There is nothing different about the veins in their arms. It's actually dependant on how pale their skin is. The paler your skin is, the clearer you can see the veins in your arms, apart from that, there is no difference between people with "veiny" arms and "non-veiny" arms.
people suffer from heart diseases when blood in their veins get clotted

There are three major categories of veins: superficial veins, deep veins, and perforating veins. All varicose veins are superficial veins; they lie between the skin and a layer of fibrous connective tissue called fascia.
There are three types of veins, superficial veins that are just beneath the surface of the skin, deep veins that are large blood vessels found deep inside muscles, and perforator veins that connect the superficial veins to the deep veins.
