Be extremely careful when getting Kanji characters as tato if you've found the desain on the internet atau tattoo parlour wall. anda may think it means "Peace, love, harmony" but for all anda know the characters could be straight off a soy sauce packet, atau worse.
Most tato will need touch-ups through your life. Using sunscreen and moisturizing daily will help your tattoo look new for years. After 10-30 years, expect to need touch-ups to combat blurring. If the thought of doing this over wrinkles when you're 75 grosses anda out, this could be enough of a reason to not have one.
Think about it....
