A naturalistic philosophy. Secular humanism is philosophically naturalistic. It holds that nature (the world of everyday physical experience) is all there is, and that reliable knowledge is best obtained when we query nature using the scientific method.
Cerebrospinal fluid rhinorrhea (CSF leaking out of the nose) following a traumatic injury is classified as immediate (within 48 hours) or delayed. Of patients with delayed CSF leaks, 95% present within 3 months after the injury. Most patients with an injury causing CSF leaks are identified within 48 hours.
I've been recovering from a cold for a week now and after bending over to pick something up a bright yellow fluid started running from my right nostril. About 2 tablespoons of the stuff, it felt like a nose bleed. The liquid was bright yellow and watery but didn't have a noticeable odour.
