Scars vs. Tattoos

There is a lot of popular myths surrounding the relative value of tattoos and by exclusion, scars.  Here's my attempt to compare and contrast them from a semi-biased perspective

Tattoos

1. Tattoos are a personal expression.
2. As tattoos become mainstream, they lose their mystique and individualism.
3. Tattoos are perceived to mean something. 

 Scars

1. Scars are a remnant of personal history.
2. Scars are unique.
3. Scars mean something.

Scars are considered ugly, tattoos considered beautiful.  I disagree.
