What Are The Sources Of Entertainment?

Well if you like sports and are the adventurous type , you may try bungee jumping , deep sea diving , skiing or gliding.             
If you have interest in traveling , visiting a place with a new and different culture may be a good option for entertainment too.
If you like to hang out , try different clubs with friends.

Hey, i like your question ;) besides the usual generic answers for entertainment i like to create art, go urban exploring (google it sometime, it's a great hobby!), build cigarbox guitars (3 so far, i have 4 boxes waiting to be built), and taking digital photos and maipulating them in unusual ways ;) oh, thought of another, people watching at crowded places is fun too ;)
