Such as? Just because you don't do it doesn't make it retarded. All of these habits can only improve your overall appearance, so why not do them?
It's pretty well known that shaving against the grain will irritate your skin and can cause in-grown hairs.
Putting your razor onto a towel after finishing shaving will do absolutely nothing to elongate the lifetime of the blade. It's stainless steel, some excess water isn't going to do anything to it. If anything, wiping down the blade with a towel will make it go dull quicker.
It tells you to spend $60 on clippers to cut your own hair, and then goes ahead and says that you should ask your barber/hairdresser to remove ear hair and neck hair. Makes perfect sense.
There is absolutely nothing wrong with using liquid soap, no need to go out and buy a bar of soap.
Acne is caused by more things than just having dirty pillow sheets and often times can be hormonal. That acne advice is absolutely retarded. If you have really bad acne, go to a dermatologist.
I'm not even going to go over why that Clothes section is wrong, this is a thread about fashion, you should be able to see the flaws there.
The shower thing won't do much to remove smelly feet. Really heavy foot odor can occur due to other reasons than some bacteria you picked up from stepping on a towel. Have you never walked barefoot?
That toilet thing doesn't work, and toilet paper is usually placed to remove splashing.
