Is it normal to be lonely at 35?

Is it common to be lonely at this age? I don't get why it's so hard to meet people these days. I should be able to hop on fb and make a friend very easily. Everyone else has a family and here I am single and hardly even have friends, let alone be able to get them to hang out with me. Luckily I'm usually too busy to be lonely most of the time anyways, and I'd say it's the same for others my age, but it still should be easier than ever to make new friends. I don't know, do people not hang out in real life anymore?
