Considering that she was writing from liberal hell, her experiences are very believable.
I also live in liberal hell, and such reports about medical "professionals" are not surprising. At 49 y.o., still racing bicycles (road, track - the velodrome at Blaine), I get these looks of "yeah, sure you do that" from the "professionals". I'm supposed to be on the big slide downhill already. The only exercise I'm supposed to be capable of is some lowest common denominator routine at Bally's.
Fortunately I found a doctor used to dealing with athletes, including older athletes, and also does the Birkie (looong cross country ski race) every year.
