Are you worried someone could hack into your computer? What could you lose if someone hacked into yo

I think there is a high possibility that someone could hack into my computer. There are many competent hackers these days, and they even hack into government\'s computer or bank\'s account which are protected by high and tight security. Therefore, it will be easy for them to hack my computer locked with just a simple password. However, I\'m not that worried because there is not many important documents in my computer. If my computer has been hacked, I would be quite sad because I could lose all my reports that I devote myself for the whole semester. Especially, when it is right before the exam season, I am sure I might be immensely shocked by the loss of documents. Therefore, I always send my works to my email and save them in my USB once more to relieve myself from hacking.
