For the last year or so, I haven't been able to cry anymore. And when I do, absolutely no tears come out. My eyes just water up, but there are no tears. Is this normal? Should I be worried?

Wondering if there are any negative effects to masturbation while being sick. I hear it could be a cause of lower immunity levels, is that true?

My eyes feel dry and swollen after hours of staring at the computer monitor. Is there any long range harm caused by spending both work and play time in front of the computer? I work out, and eat a healthy, low-fat diet. I don't have any other vices except perhaps a higher than normal caffeine intake.

My question is regarding eye exercises. I am short sighted and wear my glasses constantly. Recently I came across some eye exercises which claim that they can help you restore your vision. Their reasons seem convincing. But if this were true, why do the majority of people with poor vision still wear glasses. I just want to know if it's possible to restore your vision by doing these exercises? If not, is there any other way to restore vision without undergoing surgery? Finally, is there any way to ensure that my eye sight does not get any worse?

I went crazy and started masturbating more than usual in the shower and then when I got out my foreskin was swelled up. Should I see a doctor?
