4 day trips need to be normalized: our capitalistic lords have made us more accepting of fast living: an average flight consommes about 7 tons of kerosene per flight, and release 3 times as much of co2 in mass, ie 20 tons, per single flight. travel by train albeit slow, but releases way less greenhouse gas. train or airplane infrastrucuture cost comparison: only an expert consultant could wager which one of both is less costly. ever wondered why we retire at 65 on average? u would say with all the efficiencies implemented in transport and the extra work time we put we would retire earlier, yet, we only work more in older age. something is missing in the loop
