I think you like your music a little too much when you need it implanted in your breasts.
Computer chips that store music could soon be built into a woman's breast implants.
One boob could hold an MP3 player and the other the person's whole music collection.
According to The Sun he (the inventor) said: "It is now very hard for me to think of breast implants as just decorative. If a woman has something implanted permanently, it might as well do something useful."
The difficult thing about developing new products is that for something really unique, you never know how much demand there will be. I'm going to go out on a limb here and say mp3 boob players aren't in high demand. And anyway, if I was going to have a device planted inside me, I would want something more useful than an mp3 player.
