Don't talk such utter bollocks. It's dangerous to give out misinformation like that.
All depends on your skin tone etc, and you NEVER do one 6min session followed up by a 12 min. You're supposed to build up gradually, and never more than once in 24 hours, although 48 is a much better recommendation.
Also, never do more than 20 in a year, and if you are very fair skinned, stay away from them.
That's info from the Health and Safety Executive, so pay attention to it.
