Dr. Aubrey de Grey is a biomedical gerontologist and the founder of the SENS research foundation which aims to find technologies that can repair the various types of damage that occur during the aging process. In this episode Rhonda and Aubrey discuss the types of damage that cause aging, how aging results in a decrease in the capacity to repair damage, what role epigenetics play in aging, how people age at different rates, chronic inflammation as a driver of aging, factors that are in young blood that repair damage, the role of nutrition in aging, and recent technologies such as CRISPR, induced pluripotent stem cells that will advance anti-aging research and more.

The effect of air quality on sleep The effect of low-level noise on sleep fragmentation Whether or not time in nature transforms sleep quality Could melatonin supplementation increase REM sleep — at the cost of decrease deep sleep? How my sauna and hot tub routine preps me for sleep Is there evidence white noise helps sleep and can calming music curb pre-sleep ruminations? The differential impact of morning vs. evening light in slow wave sleep Can adjusting our body's thermal cues unlock deeper sleep? (increase deep sleep) Improving sleep with science-backed heat therapy protocols and how my sauna and hot tub routine preps me for sleep The four pillars of sleep How much sleep is enough? (from newborns to older adults) The surprising lifestyle factors that synergize to maintain glymphatic clearance in aging brains (sleep, exercise, and omega-3s) Are modern lifestyles and "social jetlag" turning us into shift workers? Building resilience against circadian disruptions Five immediate steps to enhance sleep quality tonight How long caffeine stays in the system The effect of alcohol and marijuana on sleep, particularly REM sleep
