I also figure that morphing has benefits in normal life as well as what you'd do as an animal/different person. You'd be able to take more risks and do dumber things without worrying about it.
For instance, I'd really like to learn how to do a backflip. However, I don't have access to a trampoline or anyone or place I could go to for help. I'm afraid to do it on the ground because I could seriously injure myself. Doesn't matter now, if I pop a disk or get partially paralyzed or something, just morph and demorph.
Party hard, get drunk. Morph, demorph, sober for the next day and no hangover. Friend has a contagious disease? Who cares, go help him. Diagnosed with cancer? Miraculous recovery. STD's? Pfft.
Aside from the risk of the two hour limit, morphing has no downsides but so many benefits. Actually nevermind, my main concern would be the fact I'd morph alone, and if I get overcome by the morph's instincts, I'd be screwed and end up trapped.
