I was born in 1949 and Dettol was woven into the fabric of my childhood in a comforting way, a few drops in the bath to soothe cuts and bruises, a dab of Dettol on cottonwool to clean a scrape. I Iove the smell of it to this day.
On to my competition entry: I avoid crowded places, don't come too close to someone who's coughing or sneezing, wash hands properly and (I know there's no evidence that you can "catch a chill") I keep my neck warm and my chest covered 
I haven't had a cold in a long time, but if I start with one, I'm straight on to Vitamin C and Zinc tablets.
