Potentially going backwards it can be of help, potentially. If they identify a certain group of genetic factors that we all share, they might understand based on those factors what we actually suffer from. To be honest, I was never too interested in the Baylor Study, I anticipate at least some findings from the Harvard study, that can help scientists investigate even more based physical symptoms and blood work.
Example- that dermatological study I posted where doctors were alarmed that an increasing number of men who took finasteride developed melasma. That’s an actual symptom that leads to more answers about what our bodies and why our bodies are reacting a certain way. I think finding similar physical conditions will lead to an answer eventually
