Pictures in the mirror reflect the future you
You can see what you used to look like by gazing at old photographs. The only trouble is they may make you reflect on years of debauchery and then, as these photographs above show, it is too late.
The Wicked Queen in Snow White had a mirror that told the truth, but this mirror will tell the ugly truth — five or 10 years on. It will offer a reflection of the future after years of binge drinking and junk food have taken their toll.
