1.Lower Sun Exposure: Before 1970, fewer people spent time outdoors, as people typically spent most of their time working and living indoors. Sun exposure is the leading cause of skin cancer, and with less time spent outdoors, people were less likely to develop skin cancer.

2.Modern Technology: If people did spend time outdoors before 1970, they weren't as likely to be exposed to dangerous UV rays during the day due to modern technology such as air conditioning and window tints, which protect against the effects of UV radiation.

3.Less Access to Sunscreen: Before 1970, there were no widely available sunscreen products and limited awareness about their use and effectiveness. This lack of access and knowledge further reduced the risk of skin cancer in this era.

4.No Tanning Beds: Tanning beds were not widely available before 1970, so people did not have access to the same level of UV radiation that they do today. This reduced the risk of developing skin cancer.

5.Lifestyle Choice: Fashion choices such as hats, long sleeves, and long pants, as well as umbrellas, were widely used before 1970, providing additional protection from the sun. This could have further reduced skin cancer risk.
