It's hard to find veins in people with FD. Although I'm sure many people can relate to this strip! Below is last week's strip too - I was so busy with GNM stuff, no time to post everything:
Usually people with FD may faint if suddenly standing up from laying down and vice-versa. Patients go on a "Tilt Table" - a table that slowly tilts from vertical to horizontal - to measure changes in their system.
Unlike suburbia, bushes are rare in the city. There are some trees here and there, but unless you're Bugs Bunny, not able to hide behind.
