I also recall someone saying the average life expectancy on putting foot off the skids in Nam was about 45 seconds so, sadly, I suppose you didnt have all that long in which to be bored.
I worked on a tanker supplying JP4 aviation fuel to south nam during the war, I was saddened by how many Huey personnel missing/dead between each two week run to NhaBe, Danang & Qui Nhon - they really didn't have time to get bored
