Try to get pregnant when you are older: Women who are older are more likely to have twins. Women over 45 have a 17% chance of conceiving twins, but they also have a lower fertility rate so it probably won’t make sense to wait until you are older just to conceive twins. Still, if you are older and are able to conceive, you are more likely to have twins than someone younger. The reason being is most likely related to the fact that older women start producing higher levels of FSH , follicle stimulating hormone. FSH is a hormone that tells your ovaries to start maturing an egg for ovulation. As you get older, you have less eggs and lower quality eggs, so to compensate your body starts producing more FSH. This increase in FSH production may cause an older woman to be over stimulated and result in the release of more than one egg during ovulation; thus, increasing the chances of conceiving twins.
Shale gas is natural gas produced from shale . Because shale has matrix permeability too low to allow gas to flow in economical quantities, shale gas wells depend on fractures to allow the gas to flow. Early shale gas wells depended on natural fractures through which gas flowed; almost all shale gas wells today require fractures artificially created by hydraulic fracturing . Since 2000, shale gas has become a major source of natural gas in the United States and Canada.  Following the success in the United States, shale gas exploration is beginning in countries such as Poland, China, and South Africa.    Because of this increase in shale production, the United States is now the number one natural gas producer in the world 
If you suffer from occasional insomnia or if it’s a nightly battle for you, you’ve likely looked at all of the natural solutions currently out there. You may have even tried some melatonin supplements, and if you’re like many individuals, had some disappointing results. While research has shown the body’s naturally-produced melatonin helps regulate sleep, synthetic melatonin has proven less than impressive. One thing that has been virtually ignored, however, are the foods that are able to increase the body’s natural melatonin production.
