Longevity & Aging
The biology and measurement of aging: biological age, epigenetic clocks, healthspan, the medicines older people take, and what circumstance does to how long health lasts.
Hemoglobin just over the anemia cutoff linked to more deaths in half a million UK adults
University of Glasgow researchers followed 477,876 UK Biobank adults for a median 13.6 years. Death risk was lowest 1 to 3 g/dL above the WHO anemia cutoffs, but the study cannot say whether low hemoglobin does harm or signals illness.
