I find it hard to believe: "Studies show that loneliness is associated with morning surges in cortisol, the stress hormone, and increased vascular resistance, which results in higher blood pressure. They also show the lonely drink more, exercise less, get divorced more often, and have more family estrangements and run-ins with the neighbors. And they’re fatter."

I'm alone for last few months, ie not in relationship and without too many friends, and my live is much more better.

I eat much healthier because there are no conflicts of interests, so I don't have to reward myself with junk food. Also, I have much more free time so I'm swimming every day and I don't feel bad I spent few hours just walking and thinking about my life. My blood pressure is now lower than ever.
