> Actively avoiding human shit or fresh vomit every morning on the sidewalks and keeping an eye out for needles everywhere (watch where you sit on the bus) really just leaves you tired and unsympathetic.
In addition to the dump dodging and vomit avoidance, you have to keep an eye on every shifty character in Starbucks or on the street to make sure you aren't going to be another victim of an intentional or inadvertent stabbing. Its getting to the point that for the safety of myself and my loved ones I would recommend commuting by vehicle and make walking around the city the exception rather than the norm.
