Tattoo artists/tattoo knowledge

I'm wondering if anyone that works in the tattoo industry or maybe if anyone just has some knowledge on this subject can help me. I would like to get a tattoo that's strictly words. I currently have 5 tattoos and I'm well aware that tattoos age and never look the same after 10, 20+ years as when they're fresh no matter how much you take care of them. What should I know to avoid when tattooing words to avoid it looking bad/like a blob as I get older? Are there certain areas of the body to avoid with this kind of tattoo?
