Hmmm...
I think this:
Ultimately it doesn't matter to me. I really don't care how thin or how big a person is. What IS important to me is the lifestyle of a person - but only to a specific degree that I want to explain.
A person has to care about their own body the way we care about our PCs and Cars, etc. because it ultimately is a machine. That doesn't mean that it HAS to look one way, but it means that an effort has to be put in to keeping that heart pumping, to keeping our leve of health up. A person does not have to be ripped to be healthy or have flat abs, and more often than not this doesn't apply to "thin girls" because they are too busy thinking everything they will eat will make them fat and some rush to run on a treadmill after eating what amounts to nearly nothing. They, to me, are unhealthy simply because they do not make concrete efforts to ensure their body is getting all it needs. A lifestyle like that is unsustainable, and surely later on they will get sick of it and allow a worse type of lifestyle to affect them, which will ultimately lead to the atrophy of their muscles, the loss of bone density, increase of problems assosciated with lethargy...thus effectively making them "fat".
Being healthy is someting that shows the effect of the body 5% on the outside, and 95% on the inside...and the inside is much more easily affected than the outside.
I'm not a thin ripped guy, but I try to do physical exerscise 3x a week or so and I DO have a belly. Sometimes I can go go 1x a week, and other times i can get up to 5x during the week. I will play lots of tennis, run 4-5 miles , do tai chi, racquetball and a variety of other things because of two reasons:
a) As a Biomedical Engineer I understand the physiological IMPORTANCE of trying to keep myself fit. I understand what the effects of being over weight are on our body from basic back mechanics to the way our body biologically deals with doing someting such as eating too fast. And to be honest -- being too overweight with no physical exerscise isn't a good thing.
There is a health incentive, which is ultimately the BIGGEST key factor, to exerscising and wanting to stay fit.
b) To help yourself feel good about yourself. This isn't about showing off or wearing tight cloths to attract people (which i actually don't like) but the pure biological fact that exerscise will cause you to have "natural highs" more often, and that sunlight elevates your endorphin levels. Tell me who has worked out and REALLLY did not enjoy it afterwards? Or better put, who has exerscised for about 2 weeks continuously and then found they didn't like it?
There are MANY benefits to staying active...but to be active doesn't mean you are thin. Give me a person who is not the thinnest around, but makes a REALISTIC effort to exerscise (ie: not 7x a day for 2 hours...later on in life it gets too hard to maintain that when we get so busy) so that later in life they can minimize loss of muscle tissue, loss of bone density, myelin degeneration, high cholesterol OVER the girl who is extremely thin but is adversely affecting her health when you know that ultimately her lifestyle cannot be sustained and she will bloat up because she WILL eat more in the future.
If a girl doesn't see that importance as well, then there might be a problem because if they aren' willing to attempt to stay HEALTHY (i seperate this from tin b/c many thin women are not healthy) now, what makes them want to stay healthy later? so a girl weighing 300 lbs now, I don't see any change in the future and I would see a compatability issue. But at the SAME time, a twig also violates that rule to me if it is apparant that they are not healthy because to much exersicse and too little food affects you adversely...and what is to say that she isn't just trying to "nab" a guy and then later get lazy?
Its about being trying to be healthy, not trying to look thin. And people with bellies (like me) are much more healthy than guys or girls who are proud of their size zero and eat lettuce all day long...because one kns how to make life enjoyable and long lasting whereas the other is totally clueless and potentially shallow.
