Sorry but I think this does not really sound convincing regarding longevity, since there is no consideration of the net effect in light of the well-known positive health benefits of being outdoors. At risk of stretching my bed analogy, there are probably things you could do to mitigate risk of falling over in your home if you do get out of bed, such as wearing a helmet...

See eg this article:

https://www.ncbi.nlm.nih.gov/pubmed/26992108 "Avoidance of sun exposure as a risk factor for major causes of death: a competing risk analysis of the Melanoma in Southern Sweden cohort"

"CONCLUSION:

The longer life expectancy amongst women with active sun exposure habits was related to a decrease in CVD and noncancer/non-CVD mortality, causing the relative contribution of death due to cancer to increase."
