LOL, thanks guy's that explains everything. I didn't look to see if they was sick i just assumed after seeing their health meter wasn't full that they was sick, i guess if they are sick they will do things like sneeze and/or cough etc will it tell you on the panel or in the details screen if they are sick?
I lost my first villager aswell over night so sad because he was only 21, i forgot to put the game on half speed, i don't know why he died i was presented with a skeleton upon loading the game.
On my test game i was presented with four skeletons but they all died of old age so that wasn't to much of a problem is their anyway to find out what they died from?
