Longitudinal Growth and Development Study

So, I have been on Zity for years and I have occasionally mentioned that the prime spark for my fetish seems to have been a program I was in during my adolescence that involved a lot of things but that particularly involved Tanner stage assessments. However, it was only this year, all these decades later, over the holidays, that I was going through some old boxes of documents that had been kept (but not well organized) by my parents and I learned many of the specific details of the program, which was multigenerational.

On the off chance that anyone here, male or female, may have had any connection to the Fels Research Institute studies which began in 1930 but only ended in 2018, I would very much love to hear from you. Please feel free to send me a DM.
