Average lifespan of a business jet?
Not a problem, Monty...we had a couple of Fat Alberts on the line when I
"retired" from PSA in the late '60s. The 737 was BUILT for the milk
runs...our longest run was an hour; many of them were 45 minutes or so. You
can get a dozen cycles a day in at that rate and that was 40 years ago.
A "cycle" is depart, gear up, gear down, arrive. 99.999% of the time that
also means a pressurization.

The number of pressurizations is one factor. Something like 10,000 (that
would be 10,000 pressurizations, not hours) is getting up there.
I have recently flown a 737 with over 74000 cycles.
Is taking off, flying up to altitude, then landing, one cycle?
10 Cycles Per Day (x) ...
10 years (3,650 days) = 36,500 cycles
20 years (x) ..10 c.p.d. = 73,000 cycles
25 years (x) ...8 c.p.d. = 73,000 cycles
40 years (x) ...5 c.p.d. = 73,000 cycles
WOW!
