This is a good thread and one I'd like to throw my 2 cents into.
A couple weeks ago my grandpa died. We were at the wake and they had many pictures up of him throughout his life. There was one in particular that grabbed everyone's attention. It was a portrait of him when he was a young man. EVERYONE that saw that picture said he looked exactly like me. It was uncanny. This is not coming from me. I had so many people approach me and tell me this that it was starting to get annoying and embarrassing. Anyway, the point being that the strong resemblance had nothing to do with a past life connection. It was entirely genetic.
I know there are many people out there, even credible researchers who strongly believe that there are physical traits that follow the soul matching them in appearance with their past life selves. I will admit there is photographic evidence out there that even I have to admit that the resemblence is striking. However, I have a hard time accepting that the basic structure of someone's physical appearance is anything more than genetic in nature.
I do have a theory as to why these strong resemblances occur from one lifetime to the next. The answer is - style. We are all creatures of habit and we all have our own unique styles. We tend to keep eating the same foods, listening to the same music, watching the same movies, and of course wearing the same clothes. I don't know about you guys, but when I go shopping for new clothes I know what I like, know what I'm used to, and I know what I'll likely take home with me. My wardrobe is pretty consistent. I have my signature style. (or lack there of : angel )
Why wouldn't it be that way selecting bodies for our incarnations? Why wouldn't we stick to some kind of familiarity? I recognize personalities are different. Some people I know you could set a clock to their habits, others are trying new things everytime I turn around. That might explain why some have consistently similar appearances from life to life while others drastically change.
Of course this is merely my opinion. I could be way off, but it makes sense to me.
For me it seems that for body build an average to slender build has been consistent for me. Also I tend to go with darker hair colors. One example of a little variance from this would be in my life as the French girl my hair was closer to blonde. In my two American lives prior to this there was a bit of a difference between the two. In South Carolina I was a red-headed woman and very well-endowed. In my most recent life I was a short and petite girl with dark hair and brown eyes, and was very much
not well-endowed.
In this life I'm above average height, an average build, brown hair, and have a hazel colored eyes. To be honest, I don't like being as tall as I am. Though I'm not abnormally tall, I feel like I've never been this tall before, and I do at times feel some discomfort with it.
