@310843B I have no idea, have never smoked myself, but had a Dad who died - eventually - from a heart attack, but had bad emphysema, but I wasn't 'over there' most of the time, so didn't see the toll his smoking took. NoBoDe was actually quite cross with me - for not having listened enough when he told me about his symptoms . . . not a nice thing to happen to me on New Years Eve - but I slept it off . . . looking forward to a Good New Year. Happy New Year, Numbers Taurisk
