Weird feats and you - a question

Probably being able to handle fire and lava like I used to. The fire in this world is different from the one in mine, but regardless, the climates I can tolerate in this world are quite limited. I used to take lava baths in my old world, but in this one I can hardly deal with 70 F weather. So being able to have that contact with fire and lava again would be nice, because it is something that feels very homely to my mind, and yet is completely inaccessible unless I want to burn to a crisp.

Being able to run up to 45 miles per hour would be great. The fastest anyone has gotten with a human body on record is 27.8 miles per hour (top speed reached by Usain Bolt). The average speed is 7.25 mph. Why? In my case, speed is a huge part of being a sighthound and I'm lacking due to having a human body.

Ohh this is a good one. I'm so curious what information I'm missing out on.

Just being able to move around quadrapedally without a weird posture would be nice. I can sometimes get my shoulders in a comfortable position, but there's not much I can do about having human femurs.

Shape shifting, then i could have everything else! And i could be myself for once…
