I no fitness expert, but I used to sauna lots. Try not to get caught up in 'I weigh this amount so I should do this' blah. I'd say if you're drinking lots of water while you're in there, just listen to your body, it'll tell you when times up :).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
