I'm surprised you said he couldn't afford Switzerland, I thought they weren't supposed to make money off help with dying? Are they secretly making money then, or is there paperwork that's expensive to file?
The last time I checked Switzerland was still your best bet to exit with dignity rather than spending the last several years of your life as a bedridden vegetable kept barely alive with drugs, like several of my relatives were. As an (apparently) rational person I really can't fathom why we put people through this slow torture, is it based on some medieval religious superstition or something?
