“Although we often have little control over the genetic and environmental factors, lifestyle is an easy target for influencing how we age. In this clip, Dr. Elissa Epel describes how even small lifestyle changes can have an effect on telomere length and healthy aging to compress morbidity.”

“Genetic studies show that the association depends on the number of copies as well as age, sex, and population background. This makes APOE4 useful context for understanding risk, while an individual's future health depends on more than the genotype alone.”

“Elevated homocysteine levels often slip under the radar during routine checkups, yet they quietly raise our risk for heart disease, stroke, high blood pressure, Alzheimer's, and even shorten our lifespan. About one in ten adults carries a common genetic variant that makes it harder to clear homocysteine from the body.”

“". Alcohol use disorder has complex environmental and genetic causes and is associated neuropsychiatric diseases such as depression attention deficit hyperactivity disorder, psychotic disorders, and dementia, among others.”

“By inducing positively valenced, and sometimes even life-altering, psychological experiences, psilocybin may leave "quantifiable marks at the molecular genetic [and] epigenetic level."”

“Ten days after the onset of symptoms, viral genetic material is still detectable in their sputum, but the risk of spreading the virus is minimal. Concerns about the potential for re-infection began circulating in the media after COVID-19 patients in Korea tested positive for the virus shortly after recovering from the disease.”

“Dr. Steven Horvath, a professor of genetics and biostatistics at UCLA, analyzed large data sets of DNA methylation profiles to derive an algorithm based on the methylation patterns at 353 CpG sites.”

“These variations are common in people of East Asian ancestry (prevalence of low-alcohol-tolerability alleles between 21% and 69%) but rare in people of European descent (prevalence of 0.01% to 4%). People with these genetic variations experience facial redness/flushing, nausea, and a rapid heart beat when they drink.”

“Several genetic variants of BDNF were evaluated, and while the Val66Met variant was associated with women with eating disorders, other variants showed an even stronger association.”

“APOE4 is the strongest common genetic risk factor for late-onset Alzheimer's disease, while physical activity, sleep, blood pressure, and diet remain important modifiable influences across the lifespan. Nutrition may offer additional support.”
