BB and I were discussing how the barista at our local café had a lovely tan, even though we expected her to turn burn red in the Sun due to her being from UK. Our conversation moved to a skin index and where she would fit in that. Minion1 was listening in and needed to add his two cents worth. He informed me that he knew what the skin index was and that the skins types were “Dark, tanned, whitened and charred”. Pretty apt description when you think about all the skin colours around due to tanning. If you are interested in the various skin types have a look here .. http://www.arpansa.gov.au/RadiationProtection/Solaria/Offline/05/07.html
