The Diary Of A CEO with Steven Bartlett

The Mitochondria Scientist Dr Martin Picard reveals why stress is secretly burning 60% of your daily energy, the science behind reversing grey hair, and why your mitochondria - not your genes - determine how fast you age!

Dr Martin Picard is a Professor of Behavioral Medicine and Director of the Mitochondrial Psychobiology Group, who specialises in how stress, emotions and lived experiences affect your mitochondria. He recently published the world's first map of mitochondria in the human brain and is also the author of the upcoming book, ‘Energy’.

He explains:
◼️Why depression is really an energy problem, not just in your head
◼️Why eating more food won't give you more energy, and what actually will
◼️How training for a marathon can double the mitochondria in your muscles
◼️Why people with a strong sense of purpose have more powerful mitochondria
◼️Why cancer cells abandon their mitochondria, and what it means for treating them

Women’s sex lives are being quietly destroyed, and their doctors don’t even know it… Sexual medicine specialist Dr Rachel Rubin reveals the hidden hormone crisis, how prescription drugs can impact sex, and the treatments most doctors aren't prescribing like Hormone Replacement Therapy.
Dr Rachel Rubin is a board-certified urologist and sexual medicine specialist, and one of only 80 doctors in the US trained to treat both male and female sexual health. She recently played a pivotal role in the removal of the FDA's boxed warning on menopausal hormone therapy - one of the most significant healthcare policy changes affecting midlife women in decades. She is also the Founder of Rachel Rubin MD and Director-at-Large of the International Society for the Study of Women's Sexual Health.
She explains:
◼️ Why most doctors fail women on sexual health, and how to build a team that won't
◼️ Why menopause is a whole-body hormone event, and the treatments that actually help
◼️ The physical barrier blocking orgasm in 1 in 4 women, and how to fix it
◼️ How a tight pelvic floor could be ruining your sex life
◼️ Why your sexual pain and low libido are physical problems your doctor keeps missing
