IVF is usually used by women or couples who are struggling to conceive naturally, and it involves the retrieval of eggs from the ovaries, which are then fertilized by sperm in a lab, before being transferred into the uterus.
Climate change forced former supporters of the industry into a rapid about-turn, to the point that some now see coal-mining as a crime against humanity, rather than the beating heart of the working class.
'I realise I hadn't had an education, and I tried some side jobs, 9-5 jobs and none of it worked. So I did a bit of study on how to work in something you love. That was social media, and it's really started to take off in the last year.'
And it turns out her day of fun in the sun, which included swimming, strolling and a relaxing massage, was just a warm up for another night behind the turntables as the guest DJ at the trendy LIV nightclub.
Kourtney didn't clarify in the clip if she is still menopausal, or whether she was just experiencing menopause-like symptoms, which include irregular periods, hot flashes, chills, night sweats - and weight gain.
In 1974, there were still a quarter of a million miners employed in Britain. A decade later, it was down to 130,000, when Arthur Scargill made his fateful decision to take on a much better prepared Conservative government led by Mrs Thatcher.
By the time I was born in the 1960s, oil, followed by natural gas, had become the mainstay of home heating. But still a pall of smoke hung over the older houses in Canterbury, where I grew up. I still associate visits to my grandparents in a Nottinghamshire mining town with an acrid smell that pervaded the countryside for miles.
I believe I was 39. Top notch, top tier. I think it gave me a feeling of, like, taking a deep breath. You know I was 39 and I was about to turn 40 and everyone was like, "If you're going to do it, you've gotta do it now."
At that time, five-sixths of the world's coal was mined and used in Britain. At the industry's peak in 1913, there were 3,024 deep mines in operation which produced 292 million tons of coal and employed 1.1 million miners.
Without it, industrialisation would rapidly have stalled as Britain ran out of water power for its mills and charcoal for its iron production. While coal picked up on the foreshore in County Durham had been shipped to London since medieval times, it was the greedy furnaces of the industrial North in the late 18th Century that really sparked off the industry.
The switch from coal-burning to gas, oil and electric heating in British homes has led to sulphur dioxide levels in the air falling by 98 per cent since 1970, and fewer soot particles no more than 2.5 micrometres in diameter by more than three-quarters.
The punk rocker shares Landon, 18, and Alabama Barker, 16, with his ex-wife Shanna Moakler, and he also helped raise her daughter Atiana De La Hoya, 22, from her marriage to the boxer Oscar De La Hoya, and the two have remained close.
While householders today worry about the environmental damage committed by cars and wood-burning stoves, the air was filthier back in the 1950s, before air-pollution records were kept, when London smogs blotted out almost all light.
The last mainline steam train service ran until 1968. Throughout the 20th Century, coal was the mainstay of electricity generation. And as late as 2012, it still provided nearly half of our electricity.
A proposed coal mine at Whitehaven, Cumbria, which was granted the go-ahead by the Government in December, was bitterly opposed by climate-change protesters, in spite of the fact it will not be producing coal for power stations or open fires, only coking coal for steel-making.
'So I was like, "Okay everyone, stop rushing me. I don't even know if I want to have another kid or if that's like in the future or whatever." And having control over my body, it just gave me, like, peace of mind.'
In the teaser - which appears to have been leaked on Instagram before quickly being deleted - Kourtney claimed that her attempts to conceive a baby via IVF 'put her into menopause', while also causing weight gain that saw her flooded with 'rude' comments from social media users pointing out her changing body shape.

In 2008 one of the first studies into the long-term effects of follicle stimulation concluded that IVF 'appears to have no lasting impact on the timing or symptoms of the menopause', however, the research is yet to be cemented.
