This great slideshow on the NY Times site shows side-by-side photos of identical twins. It’s supposed to be about the effect of environmental factors (smoking, stress, extreme tanning) on the appearance of aging.

I don’t care so much about the scary implications about wrinkles and eyebags, but it is fascinating to go back and forth between two sames-that-are-not-the-same. It does something itchy to my brain.

These genuine twins photos (taken at Twins Days!) are like looking at computer-morphed images of the same person. Like the ones used for personality tests to see what traits you respond to in the opposite sex.

I like introverted, feminine dudes. Big surprise there.
