But the seed had been planted two years prior when my dad, who was a colonel in the Army, was like, so what do you want to do when you graduate from high school? And I said, I wanted to be an Army Ranger or a Navy SEAL. And he said, well, you can't. And I said, well, why can't I? And he said, because you're a girl. I was like, what does that mean?

And he said, well, they don't accept women in the SEALs or the Rangers. It's a special ops and they don't accept women. And that was the first time in my life I've ever heard that I was limited because I was a female and I didn't match what the norm was. Because my whole life I'd been playing with boys, competing against boys. I mean, like it was just a normal.

It didn't matter if you were a boy or a girl. It just was what you wanted to do. And then when my dad said, well, you can't because you're a girl. That was the first seed that had been planted and really made me upset and said, well, this doesn't make sense.

And then when I got to university and that happened, that was the definitive seed that just really pushed me into the whole academic and sporting career that I've led over the past 20 some years.

I've been a competitive athlete most of my life. So I would, I race bikes professionally. I did Ironman, I did XTERRA, and I'd have teammates who would ask me questions of how am I fueling? How am I going to perform my best? So we'd take those questions into the lab.

So we were looking at how do we optimally fuel or how do we optimally acclimatize the heat when we're at a point in our menstrual cycle where we don't have as much heat tolerance. So that we see when progesterone comes up after ovulation or core temperature comes up, we don't have as much heat tolerance. So how do we adjust for that?

So there are a lot of questions that would come through just by the nature of being surrounded by competitive athletes and being a competitive athlete. So we look at things like, we know now that when you want to do... acclimatization to the heat.

And I bring this up because if I live in New Zealand in the wintertime and I'm trying to train for something like Kona, that happens in Hawaii, and we max out at 10 degrees Celsius in the winter, but we have to face 40 degrees Celsius to race Ironman. And we get into a sauna and we want to accommodate for that heat. We know that men can go seven days in a row and be fine to then race in the heat.

But for women, it depends on which phase of the menstrual cycle. And if you are going in the high hormone phase, then we say, okay, well, you don't need a primer. You can just go in and do nine days in a row.

But if you start in the low hormone phase, you actually have to go into the sauna for five minutes, come back out, and then go back in and do that during the low hormone phase for nine days in a row.
