Gcap,
The rest of us do give a ****. If you really DON'T give a ****, then it's time for you to go!!
By the the way; the 48 to 52 statistic was based on a retirement an average retirement age of 55 by the likes of British Airways, Cathay, Pan Am and TWA in the the late 1970's!!
There is NO valid data on what you are proposing except that the average long haul, back-side of clock worker is normally dead at 67!
