i rollerblade but the falls are the same sort of. anyway i know the feeling.
on the other hand, i just studied for like 8 hours and feel like if someone with an endocrine disorder came up to me i could fucking treat them. Cushing's syndrome (or disease, they're different!). Addison's disease? no problem. Well, both of those are pretty big problems actually but you know. And yes, if you're familiar with those, you can tell the last section I just read was about how important the CRH-ACTH-Cortisol system is.
just had to get that off my chest. *awaits biology pun*
