Trouble with flying is also the fact that the environment is not like sitting in an office chair on the ground for 12+ hrs.
The cabin height is circa 7000 ft. The humidity is only about 20% and the continuouse noise even with noise cxd headsets is always there. The human body is working hard to cope with the environment. Now do that for a few days with reduced rest times & finally on the final day do one of those stand by flight scenarios of 22 hrs. Do you really want your wife & kids lives in the hands of that pilot doing 160 miles per hour judging the aircraft touch down to within a few ft some 30 ft away in limited visibility or gusty wind.
Think not!
Am amazed anyone thinks it is safe.
