Who am i interviewing?

I am interviewing my father because he lived in a very different life than ours. He had 3 other brothers and a mother who wasn't as overprotective as the ones today are. He also served in the canadian Military as a paratrooper combat engineer and spent his life moving from province to province.  I have decided to ask him something along the lines of what would he do with his day normally. I find that this would provide a brilliant contrast to how we spend our days here and now
