This question made me sit up straight! No easy feat as I was lying in bed, 7lbs heavier than I wanted to be, with a hot water bottle in the waistband of my jogging bottoms for my crampy stomach.
I was listening to a podcast all about women's hormones with a controversial hormones researcher
That podcast was a real eye opener for me. I already knew that for women our sex hormones start to decline at around 35 years (around 30+ for men) but what was interesting was her claim that hormones are linked to longevity.
Her theory was that once estrogen starts to decline it is a signal to your body that it is time to wrap things up and that's why ageing related issues start for occur post menopause. Estrogen in proper balance (controlled by progesterone) underpins longevity and health so her advice was to 'hack your health' with hormone replacement therapy to the point that you have the hormone levels (and therefore the health) of someone in their 20s
