  1. This doesn't answer (or even ask) the question of what to do when it's already "too late": what about those of us who've already suffered severe sun damage and been diagnosed with skin cancers? Is there any level of sun exposure that's beneficial, or even safe for us? I grew up in Florida before effective sunscreens were invented, and spent my childhood and teen years out on the beach year-round. I'm paying for it now. In December of 2018 I had a melanoma removed from my right dorsal forearm along with a sentinel lymph node biopsy (all is well), and in a few weeks I'll be having Mohs surgery for a squamous cell carcinoma in situ on the superior helix of my left ear. This could involve removing up to 1/3 of the ear tissue (do NOT google this if you're at all squeamish!!!) and reconstructing a new ear from a skin graft. I've also undergone multiple uncomfortable treatments for actinic keratoses (cryosurgery, topical fluorouracil, blue light therapy). Needless to say, I don't want to increase my risk of recurrence, or develop new cancers, or incur additional cosmetic damage. I've read a lot of the current research, and there doesn't seem to be a 100% firm consensus. Right now I'm leaning toward erring on the side of caution with zinc oxide, long sleeves, and wide-brimmed hats while taking vitamin D supplements. I guess I'm just feeling particularly frustrated and annoyed right now because a co-worker spent ten minutes in my office this morning explaining to me how "according to Dr. Mercola, sunscreen is the cause of melanoma." I'm pretty low on patience when it comes to Mercola and his fecal matter of bovines, but it's hard to counter when there's still so much conflicting and missing evidence from science itself.

    CR affect on menstruation and amenorrhea?

    Hi, Kelsey-- I'm a woman but at 62 I'm post-menopausal, so I didn't feel qualified to chime in. Menopause was induced abruptly by chemotherapy for lymphoma when I was 53. I had been officially practicing CR for 5+ years before that though, and unofficially most of my life by "dieting." I never experienced amenorrhea but I kept my body fat around 17% and never dropped below that. My overall health is excellent now, but I definitely noticed rapid and dramatic aging of my skin following menopause. I've noticed a similar effect in younger anorexic women I've worked with, the loss of estrogen is hard on the skin.

    Blood Donation Fail

    I'm not eligible to donate blood because I weigh less than 110 lbs and my BP rarely goes above 80/50. But when I have blood drawn for tests I do the mental thing too, where I think Highly Stressful Thoughts to try to bring my pressure up. I have vividly visualized: IRS audits, flat tires on dark lonely roads, being locked inside an overflowing Porta-Potty, egregious wardrobe malfunctions while public speaking, etc.--but my BP never budges. All I end up with is a clenched jaw and tight bunched up trapezoids. Clinicians and machines are regularly alarmed by how low I run, not just BP but body temp, RHR, respiration, WBC count. I feel like there ought to be a prominent sticker on my chart that reassures, "She's not dead, she's probably pining for the fjords."
  4. I have nothing at all against mindfulness meditation but as a lifelong migraine sufferer I find myself bristling when I read studies like this because it's something that's so often recommended by 1) doctors who take women's complaints less seriously than men's, and 2) insurance companies that don't want to pay for treatment.

    Is a bone density test worth the $$?

    Maybe I'm imagining this, but I seem to recall reading maybe 10 years that Luigi (I think) was looking at a correlation between bone strength and fingernail strength, and that an easy test of bone condition via a fingernail sample might come of it. Any truth to this?

    Optimal Late-Life BMI for Longevity

    BMI doesn't differentiate between lean muscle mass and adipose tissue. For example I'm a 62 year old woman with a BMI of 19.2. My body fat is 18% (measured by hydrostatic displacement); yet it would be possible for me to have the exact same BMI of 19.2 but have 25% body fat, if I had less muscle and/or more adipose tissue. How does this ratio affect longevity? Is it factored in to any of these studies?

    Owning a Pet

    I've read that living with dogs helps diversify the human gut microbiota but don't have a specific cite. Roofus is a 15 yo rescued Chinese Crested and Arthur is a 10 yo rescued Cockerdoodle. Between the 2 of them they have the IQ of a doorknob, but I love them.

    Matcha Tea

    There have been some worrisome reports of small amounts of radioactive cesium 137 in green tea from Japan as a result of the 2011 explosions and melt-downs at Fukushima, worth keeping an eye on.
  9. I used to occasionally splurge on broccoli sprouts but the markets where I shop have all stopped carrying them due to high risk of bacterial contamination.
  10. Hi, Casey-- I live on an island near Seattle, and am very happy to see another female here! -Liz
  11. Same here, with some individualized tweaking of supplements, e.g., I take extra B2 and Mg to help prevent migraines even though no deficiency is indicated by bloodwork.

    Impact of Diets on the Environment

    Surely eating so much LESS has got to count for something, right?

    The View Out of My Window Here

    Thanks. It's 3 stories tall, about 250 sq feet not including the deck, so a tiny footprint. The sleeping loft is on top with windows on all 4 sides so I can get up close and personal with the barred owls and pileated woodpeckers. It's almost a mile to the nearest paved public road but only 3 miles to the ferry to Seattle.

    The View Out of My Window Here

    I live in a small treehouse deep in the forest on an island near Seattle. The view from my many windows comprises trees, trees, and more trees! Spectacular when it's snowy or sunny, but most of the time it's just a lovely peaceful dark green and grey.
