Your immune system could be down try to take in more vitamin c and wash hands more or use hand sanitizer more often.
Because you re sick.
When someone has told u he is sick, you say "whats wrong, is there anything i can help with" That's what i always say!!!!
They hardly run on time and it is easy to get sick/catch a cold if someone near you is sick.

It depends on your body immunity. A Cough actually can contain some microorganism, like viruses, or bacterias. They can transmit to you through the air. if you are in good form and not infected with HIV or have a complicated disease, then you will be fine and not sick.
because if we didn't we would probably get really sick and always feel cold.
Sure. Many people can be carriers of disease but not actually having symptoms themselves.
probally although it is unlikely someone else could get sick
Like people, kangaroos can get sick if they get wet and cold, but it not always the case.
it is always good to eat spicy food even if your sick
you might get sick, but cold has nothing to do with it.
if the cats or dogs nose is almost always dry then they r sick.
