Our body makes us unique. Naturally, a lot of our identity forms around our body. Consider the following factors:
1) Height: I read from couple sources that being tall is the single best predictor of career advancement (here is one article, which also suggests that being tall is advantageous in mate selection.)
Thus, being naturally tall would help develop a confident character in taller men (I’m not sure about tall women), while forcing smaller men to work harder at developing their success skills to compensate.
2) Appearance: Being handsome or beautiful tends to create a positive feedback loop among peer groups, which may naturally encourage the person to be more out in the public eye.
Physical unattractiveness (in one’s own perception, at least) may force the development of other attractive characteristics such as humor or kindness, or may direct the person to be engaged in less social activities.
3) Strength: body fitness and energy level naturally leads to confident behaviors. Naturally strong and healthy people would feel more confident to begin with, whereas the less healthy individuals may carry the vulnerability with them in personal interactions.
Most of us aren’t gifted with the perfect physique, and our imperfection sets us on a path to develop our identity in some unique way. Noel Tyl teaches to be mindful of how the person dresses, as well as how tall the person is and how much he/she weighs, as important considerations in determining the person’s confidence level.
Astrologically, physical strength may manifest as Jupiter’s invigoration of Ascendant, Sun, Mars, Uranus, and/or Pluto through aspects (the athletic signature may involve many of these.)
Physical attractiveness may somehow be apparent in Venus’ halo effect on Angles, Mars and/or Ascendant ruler (this may be a good topic of research), although Venus may manifest more as a humorous kind of attractiveness (perhaps there would be a sign correlation.)
While the astrology of the body is interesting to be sure, the good news is, there is a lot we can do today to improve…writing this makes me want to exercise and drink more water, for instance.
