I have never read Nitzsche although i have struggled to spell his name before in crosswords. Thank you for writing this. It has proved a great introduction for me and i am with him (and you i guess?) on this subject of suffering and the benefits that can come from it. i choose to swim outside through the winter in temperatures down to 4 degrees: it is all about finding comfort in discomfort and it makes me feel SO alive. Yep. I'm with him. Apart from when I've got toothache.
