NANOPARTICLE INGESTING from sunblock?

I am a non believer in Sun Block. I was exposed to sunlight for many years. I never used a protector and still do not use blockers. I take my sun in the mornings and late afternoon until I build up a tan then I sun all day long as my skin color is changed to tan rather then a burn. Uhhh ... Vancouver & sun ??
