You know -- bell bottoms and loud polyester shirts were a fad for a few years. Looking back now it seems ridiculous. I think the same thing about tattoos, except you can take off the bell bottoms, and all that remains were some embarrassing faded photos.

"Tattoos" -- its like bell bottoms you can't take off.

better hope your start-up pays off - so you can afford to get it removed in later life.
