I have been to Nepal, Singapore and Malaysia.
Nepal was quite a shock travelling there. Complete poverty. Everywhere you went there would be buildings falling apart, rubbish laying around and on most streets there would at least be one beggar. You would see children as young as three on the streets latching onto you until you give the some money. I did also witness two people commit suicide by jumping off a cliff which was dreadful. It really hits you hard how fortunate we are here in Australia. None the less it was an amazing experience. I got to do a seven day trek along the Annapurna circuit seeing some breathtaking sights and slso went to the Chitwan national park and did an Elephant ride into the jungle to see some baby rhinos.
I strongly recommend you go there if you get the chance it is a great place to experience.
I went to Singapore and Malaysia to play hockey for my club. Singapore is a really, really clean and touristy city, so there is lots to do. They have an amazing drink called 100 plus which basically like powerade but 100x better. Unfortunately in Malaysia I got struck down with food poisoning so i was mainly in bed or on the toilet so I didnt see much.
I would love to go to Japan and to travel Europe.
