I don't think either parent was bothered about tanning for its own sake.. though there were rather a lot of bottles of fake tan, sun oil, make you go extra brown type stuff at home, suspect they were mothers and a bit of a fad rather than a lifelong thing.
My Mum went brown easily and rarely burned, my dad despite being strawberry blonde and uber-freckly, would go a bit red if he really over did it, but would then go brown, stay brown and not burn again.
My sister has to my knowledge, never burnt, certainly never as a child so I was a bit of a shock to them... I could burn in factor 25 which in the 80s wasn't so easy to get.
They did try.. but I got burnt through thin clothing, burnt on overcast days, I got burnt in February in the UK once! I got badly blistered in Brittany one year, and again in Cornwall 10 years later so now I keep a close eye on all moles and weird skin things, I've had one removed that turned out fine... but... mm!
These days I hide in the shade, very occasionally ill nip out for five minutes for a dose of vit D, but im back in before I can feel skin burning!
