Nom, I am very sorry for hijacking your thread, and this is the last post I will make.

Here are some links that say moles don't last forever.

Some moles may not change at all, while others may slowly disappear over time.

Moles will vary over time. There may be color changes, surface changes, or begin to have hairs. There are some that will change much over time, some that will not change a bit, and some that may just disappear.

Yes, melanogenesis is something that normally happens in the body. I never said it wasn't. What I said was certain triggers can jumpstart melanogenesis which can lead to the creation of a mole.

And maybe you're right in saying that we don't yet know ALL 100% of the external triggers of melanogenesis, but we know the most common. And guess what? Puncture wounds ain't on the list. Unless you're a dermatologist currently involved in research on the subject, I don't believe you.

At any rate, a scar/mole/tattoo/divine symbol of godhood/WHATEVER is a pretty shallow reason to decide to not give blood when you can potentially save someone else's life.
