Baggage Loss

I encountered my first baggage loss after travelling for a year.

There's a reason why I never like to check in. Even if it's whatever you deem call it: Star Alliance. Its got nothing to do which airline or what Star Alliance at all sometimes. Just never secure because my backpack has no locks, no safety measures at all.So this time, I lost a green canvas bag, together with:
1. tommy colonge 100ml
2. 4 bottles of excellent wine from spain Torres torress toress :(
3. guo shi gai yao which belongs to mr lolli
4. all my notes from lectures
5. food.
6. toothpaste, shampoo, tooth brush
7. other things i cannot remember.

So, where does all this lead to? Its not safe to check in a normal bag nowadays if there is no bag? Or issit just depending on which country you visit? Comeon, its Europe. Not some poor country who need to TAKE daily life stuffs from strangers.. .-.even the luggage track system sucks. "still checking" "come back next time"confidence man, my friend. do your job, baggage tracking system. zZzzzZzz
