Sadly a tattoo is for life (unless you have painful and expensive surgery to remove it).
Do you wear the same style of clothes you did 5 years ago, of course not.
Do you have the same hairstyle you did 5 years ago, of course not.
So why do you think you will like the same tattoo in 5 years time (or 10 years time or 20 years time).
Tattoos are already beginning to look stupid on the people that have them, so why not show you individuality and NOT have one.
You wont regret NOT having one, but you may regret HAVING one.
