OMG .... I was right!!!
I was (am) a longtime Heinlein fan. But, I noticed that his later works just got ... we'll over sexed would be the best way I could phrase it.
However, I just put this down to my personal taste, and never said or thought much about it ... until lately when I posted something about what I saw as his decline. I think it might have been on this forum.
In any event, I was reading Boingboing today, when I came across this posting by Cory Doctorow.
"Charlie Stross's new novel, Saturn's Children, is out -- this is Charlie's Heinlein tribute, and unlike everyone else who does classic, adventure -story Heinlein tributes, Charlie's written a novel in the style of the late, indulgent, sex-saturated Heinlein, from the period before a cutting-edge surgery fixed a problem with the blood-supply to his brain (seriously)."
Holy MOLY!! So there really was an honest to goodness physical reason for what I noticed in his later books. I wish someone had spotted it sooner ... I mean, if I could see it just by reading those books, you would think someone would have seen it in his daily activity and dragged him to a doctor.
Ah well .... at least I'll know to avoid Mr. Stross' new novel, because I really didn't care for the "late, indulgent, sex-saturated Heinlein."
