Dear Shaun,

My favorite cousin is getting married at the end of July. I was trying to figure out how his new wife would be related to me. I then realized that I had never figured out the difference between second, third or fourth cousins and cousins once, twice or thrice removed. Can you clarify?

Why doesn’t the ink die with the cells as they flake off? Are these ink-dyed cells cloning themselves or is tattoo ink a fountian of youth for the injected skin cells and they never die?

Also would I look good with a celtic cross tatto on my hip?

And just to be fair, what about a 5th percentile Female?
