no matter how much money i would make, you will never see me flying first / business class before i'm 40

you can use the funds in like 1000 more productive ways than buying comfort for a few hours

a cost of one first class flight can buy you a year of workouts with a personal trainer which will delay the necessity for sitting in the first class for another 5 years

pure destruction of capital

trying to sound smart /doingnumbers

i've heard reports about back pains and long economy flights causing sleep problems for the next week

can't relate but if this is a case than it's probably worth it

Life starts at 40 maybe you'll find comfort in business class by then hahaha If we only getting richer day by day

I'm 39 and the second part of that might be happening to me already

You can search about this study

The Effect of Prolonged Sitting on Low Back Pain in Airline Passengers"

Authors: Dr. John M. Mayer, PhD, and Dr. Robert A. Gatchel, PhD

Maybe it's just nocebo maybe it won't happen if you won't think about it
