That's good information, however it does give me one slight niggle.

The way I see it, given that puberty didn't manage to shake my core identity and shape me into someone who isn't me, then it's highly unlikely that hormones will.

I suspect that puberty did shake my core identity and shape me into someone who isn't me (as I was prior to puberty). But as you point out, when the hormonal influx coincides with other life-changing events, I shouldn't assume it was the hormones influence.

I'm attempting to improve my luminosity at present, so hopefully my next hormonal change I'll document properly :-)
