Honestly, the best way to making friends is not to go out with the intention of doing so, but to discover what you are truly passionate about in life. Once you start to pursue your real interests, you will meet people. Friendships will naturally evolve because you'll be joined by something that you both love.
People complain that London is hard to make friends in, but I never had that problem because I am passionate about lots of things and pursue knowledge and experience.
"I think the basic anti-aging diet is also the best diet for prevention and treatment of diabetes, scleroderma, and the various "connective tissue diseases." This would emphasize high protein, low unsaturated fats, low iron, and high antioxidant consumption, with a moderate or low starch consumption.
In practice, this means that a major part of the diet should be milk, cheese, eggs, shellfish, fruits and coconut oil, with vitamin E and salt as the safest supplements."
