As a German, born roughly 40 years after the war, I still cannot fathom the atrocities we Germans brought to the world at large and to so many million individuals.
I grew up learning the history, I know my grandparents (as well as probably great grandparents) played their part in what happened. I am deeply sorry for what they/we did and even saying it these words just sound hollow in light of the magnitude of cruelty and injustice that happened.
I am very sorry what your grandfather had to endure and I am happy he survived. Though it doesn't change the past I will make sure that my children and grandchildren will remember what happened in order to prevent anything like that happening in our lifetimes again.
I currently work 32 hours / week at 80% pay and have done so for some time. On paper we agreed on 5*6,4 hours per week, but it is really flexibel. In practice I work somewhere between 32-40 hours a week and additionally take a couple of days off per month.
For me, it's the best arrangement I've ever had. If I don't feel like it or need to take care of some other stuff, I just work for a couple hours a day. Other times I really enjoy it and work 8-10. Additionally I get long weekends without having to use any holidays.
I also think my employer gets a better deal this way. Being productive 8 hours a day is more or less wishful thinking. I think the reality is somewhere between 4-6 hours for normal people. Hence I'm still almost as productive asif I were working 40h/week, but at 80% the cost for my employer. Everybody wins.
That is also a very interesting way to think about it, if I understood you correctly. Seeing the host as another player, any "bad luck" he has, should translate into myself having a higher chance of success if used correctly.
The easiest explanation I've ever heard and which immediately made me understand it was the following:
Instead of 3 doors, imagine there are 100. 99 of which have a goat and only one of which has a price behind it. Now blindly choose a door and the host opens 98 of the other doors which have a goat behind it. Would you switch your door now, given the choice?
It's easy to see that your probability of choosing a "wrong" door when you had 100 doors to choose from was much higher than choosing the right door when you only have two doors to choose from.
This method of thinking, i.e. increasing or decreasing the problem space by some orders of magintude has helped me a lot in thinking about problems and their solutions in general.
