I found this really cool thing online that lets you submit a picture and it "ages" you. It will also let you see what you might look like as various races and in a few particular artists unique styles.
Anyway, this is supposedly we will look like when we're "older adults" (I estimated 2050, a nice round number... we'll be 68):
Kinda scary, I think, since it looks like my dad + 15 years.
Check it out for yourself: http://morph.cs.st-andrews.ac.uk/Transformer/. The aging is much better than the de-aging in my opinion. You can also do humorous pictures of yourself as a few different races.
