German identical twins Otto and Ewald who simply chose different physical behaviors and look pretty different as a result.

If Ewald would stop posing and just stand there like his brother, they would look pretty much the same. Sure, you can tell he has spent more time in the gym, but it isn't that big of a difference without all the flexing. BTW, Otto has the better developed calves.

Looks to me that Otto didn't eat his Wheaties.
