Question

Which sport may become cost prohibitive over time?

Answer 1

Ice hockey! Running is something that costs very little to do, as well as pilates and yoga, which leaves ice hockey as the answer. For running, all you might need to buy is appropriate shoes, which isn't required. For pilates, it's kinda like stretching lol so you don't need much for that, and yoga is pretty much the same. For ice hockey, you need all of the necessary equipment, which would cost more than the rest of the sports. Hope I helped! :)
