Many web sites benefit from a network effect. One example is web marketplaces and exchanges. For example, eBay would not be a particularly useful site if auctions were not competitive. However, as the number of users grows on eBay, auctions grow more competitive, pushing up the prices of bids on items. This makes it more worthwhile to sell on eBay and brings more sellers onto eBay, which drives prices down again as this increases supply, while bringing more people onto eBay because there are more things being sold that people want. Essentially, as the number of users of eBay grows, prices fall and supply increases, and more and more people find the site to be useful.
Currently, carnosine has shown anti-aging effects in Drosophila flies   and senescence-accelerated mice.   The first mice study noted that a 50% survival rate was increased by 20% in animals treated with carnosine. This increase in median lifespan was replicated in the second study, which used an oral dose of carnosine (100 mg/kg/day, which correlates to a little over 8 mg/kg/day in humans, so about 725 mg/day for a 200-lb subject). Both mice studies only noted an increase in median lifespan, with no change in maximum lifespan.
If yes, you don't have to deliberately tweak your carb intake. When you start taking coconut oil, it will automatically help you "determine" how much carb you have to take to fulfill your daily requirement. All you need to do is just listen closely to your body needs. People tend to take in more calories than they need when they ignore the signals that their body gives. For example, when you see your favorite food, you would just go for it without "asking" your body whether it is hungry and does really need to take it now or not. This is when people start to gain weight.
