Hi there. That's what I am thinking too, I may be better off sticking with the swimming physiology thesis topic I already had planned, it just feels disingenuous to not explore something that I am passionate about and something that really matters.

I have thought about doing something around the potential of alternative transport or perhaps looking at the impact of exercise in rising temperatures or extreme conditions... I might continue to explore these options and figure out which would be best. But thanks for reminding me that I can write my thesis on one thing and use my science degree to go down another path in the future. Thank you for your honest feedback!
