Annika,
The 1-10 scale is popular in many western countries, including latin america.
Most american women, however, do not use it, because it is a universal measure of physical beauty only. a
And truth be told, most western women are not as simple minded as to gauge a man's appeal and/or worth by their physical attributes alone, like we appreciate a females appeal.
No no no no!!!...you devious creatures have far more calculating, sophisticated and complex measuring methods than we do.
1. Wallet size.
2. Income Status.
3. Income potential (if current income status is below par.)
4. Social status.
5. Educational background.
6. Religious background.
7. Ability to entertain you (charm).
8. Family name background.
9. Drinking habits.
10. Dancing skills
11. Home chores skills (because at one point or another most western women do expect us to perform the lion's share of the house chores in addition to being the main income earner and primary provider.)
I think that it is almost impossible to rate a person.
For me it is all or nothing. Like combination of action of numerators and denominator gives the only possible result - either it is on or off, nothing between.
May be it is deferent for woman because man's appearance is not important for most woman at all.
To really understand the scale of 1-10 Annika go to Hotornot.com
There you can rate men and women from all over the world. But most on the site I think are from America. Its a fun site to check out and you can also see how other people rate you indiscriminately if you are willing to put your best photo on there.
