No offense to the younger crowd with my next statement, but even impaired, the mind is not as developed with reasoning ability, foresight in seeing the consequences for one's actions, and feelings of invincibility--especially for males. There is a reason that auto insurance for males under 25 is atrocious and that some rental agencies will not rent to certain age groups. Even though this guy is 26, I think it is entirely plausible that this could be due to poor judgment, substance abuse, or a combination of the two. IMO, I cannot automatically jump to the conclusion that someone is impaired. I think sometimes we want to blame external factors instead of wanting to think that someone is just that stupid.
