When I was 15, I had pneumonia and my Mum insisted that I put Vic on my chest before I went to bed. I hated the sticky feeling, so I put some on my upper lip instead. I did that once and
never again! I must have spent the next 30 mins or so trying to remove the Vic and get rid of the terrible burning sensation. I didn't get to sleep for ages. What it must feel like somewhere even more tender I can only imagine!
Of course the Vic of 1966 may have been a considerably stronger version than it became in later years.
