Middle-aged individuals may be in a perpetual state of H3N2 flu virus susceptibility
Researchers have found that middle-aged individuals — those born in the late 1960s and the 1970s — may be in a perpetual state of H3N2 influenza virus susceptibility because their antibodies bind to H3N2 viruses but fail to prevent infections, according to a new study.

What I've Learned About Managing Eternity
Alec Soth/Magnum Enforced isolation isn't good for me. It's probably not good for anyone, but in my case it's particularly nerve-racking, even dangerous.
