NW_Pilot,
I totally agree that life is short. I also try to live everyday as
if it was my last but I try to make sure that other lives are not at
risk in my pursuit of happiness. I also do everything that I can to
ensure that I can wake up the next morning to enjoy whatever time that
I have left on this earth.
From what I have read so far, no one has criticized your decision
to take up aerobatic flying be it rolling, spinning or whatever. The
concern was with the use of inappropriate equipment (a non aerobat 150)
and the potential risk of other lives (unless you and your instructor
chose a totally unpopulated area for this practice).
