I don't think that effects of sun exposure significantly changed since long-long-long time ago as neighboring comment suggests. What certainly changed however is human life longevity. Your tanning strategy should work against burns, and likely has other benefits (e.g. vitamin D). But I suppose your skin still gets damaged, and it makes it age faster. Outdoor workers seem to look more wrinkled after 40 compared to office dwellers. Not sure how the sum of all factors plays here though. Does it worth to look older, but have more natural D (and possibly higher testosterone levels)? Dunno
