People like to bring up the long hours that workers in Asian countries stay in the office or workplace for to justify long work weeks in North America and Europe when needed.

In practice, they drag out their work day (eat breakfast, take showers, go to the gym, go on their phone) and don't really work significant hours in the end. Their productivity in terms of economic value produced per hour is markedly lower than most western countries. [1]

Doing real work for 65-70 hours is markedly dissimilar and very detrimental to your health. Not even sure if most people could say they could last for a few more months.
