Uh, while some folks of criminal intent may decide to shy away from deliberately choosing to victimize someone who appears bigger, stronger and more capable (physically) than themselves, it's not something I'd count upon. Sure, if you look like food, you may stand a better chance of someone thinking you're food. However ... Some strapping young man of good size, apparent health and visible musculature might still look like food to a criminal who feels they have some other advantage. Sneaking up and using both surprise and sudden violence, and especially if a weapon is possessed by them, seems to instill confidence in more than a few criminals. And that doesn't take into consideration someone who is under the influence of some mind/mood altering drug, alcohol impairment or just suffering from some mental health issue that may involve them acting violently. Trying to 'think reasonably' while imagining putting yourself in the mindset of some hypothetical criminal may distract someone from remembering that 'reasonable' isn't often the adjective used to describe criminal mindset, thought process and behavior.
