Some of that is just timing, like if the average age of death per the actuary tables is like 79, and your spouse dies at 80, you're statistically going fairly soon as well.
In essence, the average man living with a female partner would get a "nuisance" investigated, diagnosed with cancer, and (sometimes) treated; while the average single man sought treatment only when the condition was truly disturbing, and by that time it's too late to treat the cancer.

I'm actually hoping to find some place to take classes.
I am a German native and there are some good books for Germans that I studied with.
Yet, there are some excellent English resources! First, in order to learn to write (and much more if you want to), there is the excellent site www.easypersian.com. which offers 180+ lessons for free I learned to write there (took me two days). Then, there is „Complete Persian“ as a good textbook in English. I remember my first private language teacher I hired used this and it was really good.
