How sad. I know some young men who are not geniuses but they have clear cut moral values and a heart for others. Perhaps in a country like Sweden that wouldnt count for much but here in the States, particularly in red country, a good hearted reliable young man is more valueable than an intellegent one.
The kind of people of which you speak are usually very well liked by others. I suspect all else equal, that would reduce their risk of suicide.
