Most of the fear we live with isn't physical. It's the old thinking we carry from past experiences: the fear of criticism, of not being good enough, of getting it wrong. In this Mojo Monday, Carly explores how fear becomes our reality when we're on autopilot, and how becoming the observer of our conditioned responses creates space to choose what happens next.

Drawing on Krishnamurti and Morita Therapy, Carly looks at fear and desire as two sides of the same coin, and how turning that coin over shifts your focus to what you really want.

In this episode:
Why fear and the truth are not the same thing
How past experiences shape perfectionism and the fear of not being good enough
Becoming the observer of your conditioned response
Fear and desire as two sides of one coin
Doing what needs to be done while the fear runs its own course

Carly is a counsellor and coach who specialises in building psychological hardiness, which is the ability to navigate challenge, stay engaged, and take meaningful action under pressure. Her work integrates modern psychology with Eastern and Stoic approaches, helping people build resilience, live with purpose, and respond to life’s challenges with greater clarity, courage and steadiness.

 Your Fear Isn't the Truth With Carly Taylor

https://api.omny.fm/orgs/2fb3740d-3436-44af-8cc0-a91900716aa5/clips/85cbb432-2121-45d6-9f09-b4d00042247b/transcript

This conversation with Dr Leah Hechtman explores how mitochondria influence far more than energy production, including fertility, aging, brain health, and hormone regulation. It also unpacks the differences between male and female reproductive biology, the effects of hormonal contraception, and what hormone replacement may mean for longevity. Leah brings a rare mix of clinical experience, genetics training, ovarian biology research, and fertility expertise, making this a practical and provocative discussion for anyone interested in reproductive health and healthy aging.

Key topics
Leah explains why mitochondria are far more than the “powerhouse of the cell” and describes them as central regulators of physiology, aging, and even signalling patterns tied to trauma and emotion.
We discuss maternal inheritance of mitochondria and why the egg, not the sperm, carries the major mitochondrial legacy that shapes offspring health.
Leah breaks down how the oocyte actively selects sperm, using signalling, electrical charge, and mitochondrial function to influence which sperm succeeds and what genetic material is accepted.
The discussion covers declining sperm counts, including the claim that global sperm quality has fallen sharply over recent decades, along with the challenge of changing reference ranges and assay variability.
Leah shares why semen analysis can function as an early longevity marker for men, reflecting health roughly 2.5 to 3 months earlier and sometimes revealing issues long before other markers do.
The conversation explores the aging trajectory in women and men, including how ovarian mitochondrial loss contributes to menopause and how men experience a slower decline in testicular function and testosterone production.
We discuss hormonal contraception, especially starting the pill too early, and Leah outlines concerns about disruption of the brain-ovary axis, amygdala changes, and effects on mood, perception, and identity.
Leah and Paul examine menopause, andropause, and hormone replacement therapy, including why timing, formulation, and individual context matter more than one-size-fits-all messaging.
The episode also covers DHEA, testosterone, cholesterol, stress, and why hormone decline can open the “gates” to disease processes that hormones were helping keep in check.
Leah explains how microbiome health, environmental toxins, nutrition, hydration, and lifestyle all affect reproductive health in both men and women, including sperm quality, implantation, and miscarriage risk.
The conversation closes with Leah’s excitement about emerging research in embryology, reproductive biology, and the growing recognition that men’s health needs more attention.

“The mitochondria is how we transmit emotional patterns, neurological patterns, trauma patterns.”

Action items
If you are trying to conceive, consider both partners’ health, not just the woman’s.
Treat semen analysis as a meaningful health marker, not only a fertility test.
Pay attention to sleep, hydration, stress, nutrition, and environmental exposure before testing hormones or sperm.
For women, avoid assuming all contraceptive or hormone decisions are biologically neutral.
For men, think about testosterone, DHEA, and semen quality as part of broader longevity planning.
