It was a topic of conversation: does body mass index (BMI) or even height or weight vary among the sun signs?
Ayurveda would say that they may vary by Ascendant, not particularly the sun sign, but getting good data on the Ascendant is a notable difficulty, because the Ascendant depends on the birth time of day.
Getting tens of thousands of charts with that level of precision is nearly unheard of.
A psychology prof from France named Michel Gauquelin compiled thousands of charts in the 1950's and 1960's that included birth time and hence Ascendant information. I am a little skeptical of the quality of these charts, as many are from the 1800's and more worringly, many use Local Mean Time, which if you back-engineer, describe the birth time as being at 10 am or 11 am on the dot.
So, I feel I can not use Gauquelin's data. I am always on the lookout, then, for credible birth or event data, scouring data science competition sites like Kaggle for the elusive ideal data set.
I came across SoFIFA.com in that way. It gives very good data on the various thousands of professional male soccer players associated with FIFA, including their birth date and height and weight. Birth time and place are not given.
However, if I could just "scrape" that data, that would give me a way to test the conjecture that BMI or even height or weight may vary by sun sign. So, that is what I did.
