Interestingly, I remember a number of these stories quite well, but I don't think I read the collection--I think I either read them in F&SF or one of the last Terry Carr Best of anthologies. (The Haldeman story I read in one of his collections)
The ones that stuck in mind were The Jaguar Hunter (because of a memorable mocking quote and the method of jaguar hunting, which was claimed to be real), the Haldeman (cautionary tale for cyborg safety and mental health reg writers), the Tiptree (Tiptree's stories should have come with warning labels to read only with caution if you have depression), and the real winner, "Side Effects", which I found frighteningly plausible (that may have been aided by a few bad experiences with the US healthcare system and some long term misdiagnosis issues.)
