25 years of his life unilaterally exposed to sun.

Unilateral Dermatoheliosis

A 69-year-old man presented with a 25-year history of gradual, asymptomatic thickening and wrinkling of the skin on the left side of his face. The physical examination showed hyperkeratosis with accentuated ridging, multiple open comedones, and areas of nodular elastosis. Histopathological analysis showed an accumulation of elastolytic material in the dermis and the formation of milia within the vellus hair follicles. Findings were consistent with the Favre–Racouchot syndrome of photodamaged skin, known as dermatoheliosis. The patient reported that he had driven a delivery truck for 28 years. Ultraviolet A (UVA) rays transmit through window glass, penetrating the epidermis and upper layers of dermis. Chronic UVA exposure can result in thickening of the epidermis and stratum corneum, as well as destruction of elastic fibers. This photoaging effect of UVA is contrasted with photocarcinogenesis. Although exposure to ultraviolet B (UVB) rays is linked to a higher rate of photocarcinogenesis, UVA has also been shown to induce substantial DNA mutations and direct toxicity, leading to the formation of skin cancer. The use of sun protection and topical retinoids and periodic monitoring for skin cancer were recommended for the patient.

Moral of the story:
Use sun lotion!

YIKES.

Good confirmation of my tendency to stay primarily indoors.

... or why I pretty much refuse to spend time outdoors without a liberal coating of spf 50

I burn easily and have no desire to end up like everyone else in my family... with skin cancer

And to think, I was happy that I got to study on the deck today and got thoroughly burned. Excellent case study, that is such a cool presentation.

If you stay indoors though, you get vitamin d deficiency and bone disease

Maybe if you spend 100% of your time indoors. You can get a blood test to see what your D level is, and if it's low you can take supplements.
