In many places, the military traditions are based on the ethics of romantic ideas where it is the fate of young men to die in wars.
But now, in Japan, the nation with a rather upside-down age pyramid, this has been changed by elderly kamikaze soldiers: because old people's cells are not splitting as fast as those of the young, the risks of radiation are smaller. Besides, even if you get cancer at the age of 65 and die in 10 years, you anyway lose only 5-10 years of good life, while if you get cancer at the age of 30, you lose maybe 40 years.
Now, hats off to these guys. Not that I think it's really so kamikaze: we are talking about a slightly elevated cancer risk, not certain death, and not certain loss of health. I'd be more willing to work there than to eat fresh cucumbers in Germany. But anyway, who can now say that the baby boomers are just like locusts that leave nothing behind them?
