How to know if someone is lying?

Oh, hang on a minute, I just found this on a website:

10 Things You Oughta Know About…

MASTURBATION

Masturbation is not evil, dirty or harmful - it will not make you go blind, drive you insane, turn you in to a pervert, stunt your growth, give you an STD, make you sterile or get you pregnant.

Both guys and girls masturbate, it is a normal and healthy part of sexual development.

Masturbation is a very personal thing and should not be done in public places or around people who are not willing partners (think safer sex activity).

You are normal if you masturbate, normal if you wonder about it but don’t do it, and normal if you never give it a second thought and don’t do it - it is one of the few things in life that is “normal if you do and normal if you don’t”.

Masturbation may make sexual intercourse more enjoyable because you will already know what it takes to “please you”.

Masturbation alleviates stress and releases endorphens (the pleasure hormones) in to your system making you more relaxed.

Masturbation as exploration of the body is common in children between the ages of 3 and 6, in teens masturbation becomes more sophisticated and sexually motivated. Surveys have shown that 80% of males and 59% of females have masturbated by age 18.

Many experts believe that masturbation is more prevalent in the teen years due to a strong fluctuation of hormones; masturbation alleviates the strain of this build up and is a necessary part of development.

The only real problems that come with masturbation are psychological and are the result of unhealthy, religious or weary attitudes toward doing it (if you do it but are ashamed) or abnormal practices (for example, public masturbation).
