It would have been great if we all had that magical mirror. But don’t worry, technology has made it possible to find out how you will look twenty years from now.
Just go to In20Years tool, select if you are male or female. Then click the Upload Your Photo button, select your photo and upload it. After a few seconds the tool will render your elderly look.
You can then download the generated photo, share it with your friends on MySpace, Facebook (or just close the browser window for good ;) )
Note that this tool is obviously for fun only as its almost impossible to determine how will you look after 20 years, as it depends upon hundreds of factors, like your eating habits, exercise, heredity, lifestyle etc.
