Touching the chest draws further attention to it. When a woman does this in front of a man it makes the man think of doing this and is thus a highly suggestive and flirtatious act. Rubbing the chest can also be a sign of pain of discomfort, perhaps from tension and stress. Shoulder body language.
Do not let crab meat stand at room temperature longer than necessary. Whole crabs or solid meat will only last two or three days, at most, under refrigeration; however, if properly wrapped and frozen, it will keep up to three months in the freezer.
I've recently switched to boiling my crabs and they seem to keep longer in the fridge. (And taste better). I boil for 25 min, immediately cool the crabs in cold water (keeps the meat from sticking) and refrigerating any leftovers upside down in a sealed tupperware container.
