This evening, we spent time with an elderly couple, both of whom are weak and ill, trying to persuade the (typically healthier) male of the couple that he needs to spend some time in a nursing home until he shakes off the infection and gets some rehabilitation. I hope it worked.
Joe Haldeman has written some military SF, but also some material based on his experiences in the Vietnam War. Several of the out-of-print material, including short novels, novelettes and poems, are collected in a book form, called War Stories, which I finished this morning before work. Skillfully handled. I'd suggest reading The Forever War first, though.
