Alone

Yep, you are right.
I would be more cautious if I was a woman too, so no, I don't think you were too cautious. Even as a man I don't accept every invitation, and maybe I miss out on a load of other good experiences because of it. But this was a family, I tend to trust families more. Love back :)

Right you are
At least, not here in any case, I have had a great time by myself. And as a whole I seldom feel really lonely. Strangely enough I often feel more lonely when I am in a backpacker hub surrounded by other backpackers.

Wow, that was such a nice comment.
Yeah, it is hardly ever the sights that are the sticking points in my life, it is the people, and the journeys, the weird things and the good things, being stuck in mud, or climbing up mountains in my flip-flops, the conversations and most of all the generosity and hospitality of the people I meet (both locals and, I might add, other travellers). Those are the treasured memories.

Yep, you said it.
Thanks, and yeah, you are right both are sides are good, though for me, of course, the travel bit is the best ;)

Everything is possible
But the less money you have the more difficult it gets. Yes, I am sure it is possible to travel for a year with 300/1000 euros, though as you said, it would require settling down somewhere for a while and earning some money. Or going to some very cheap country and doing absolutely nothing, just eating and sleeping. I personally have different budgets for different countries, and it depends a little on what I want to do exactly. I try to minimise my costs and I think I am reasonably good at getting the most out of my trips with what I have. But I would not try and travel on 300 euros a year or even 1000 euros, because it gets very exhausting. In India my budget was about 200 euros a month, for which I could do everything, travel, eat, sleep in my own room with my own bathroom, see the sights, and even catch a flight every now and again. It just required me to travel more slow (the slower you travel the lower your budget). In Indonesia my budget is more like 450 euros a month, because it is just more expensive and also because I want to do such things as diving, which naturally push up the budget. The above budgets are realistic, if you know the ropes and still want to do the same as others, but on the cheap.

Clinical trials
A trial is as risky as you want it to be. I can only speak about trials in developed countries, I wouldn't be surprised if the riskier trials are conducted in under developed countries where the regulations and laws are less stringent and enforcement more lax. For myself, I never take part in a first-on-human trial, which means that I won't be in the first group testing a drug. Drugs are typically in a clinical trial phase for 2 years, and are tested on thousands of volunteers. Why be the first to test a new drug if you can be number hundred or so? You don't get paid more, and even if I did, I still wouldn't do it. Second, know what you are doing. That doesn't mean doing extensive research on your drug, but just reading up on the information that is provided when you go to a screening. Clinics will tell you what they are testing, what for, what the side effects were on previous volunteers, on animals, at what dosage etc. etc. Read the information so you know what you are taking, and make an informed decision based on that information. Remember that you get paid per day you are in the clinic and not on what the drug is about, what the side effects might be, or what they might or might not need to do to you on the trial. Be patient, trials come and go, eventually you will find one that you are comfortable doing and pays the right amount. Trials generally don't involve incisions, I have never heard of a trial in which that was necessary. Trials do involve taking a lot of blood from the volunteers, so you can't have a problem with needles. Depending on the trial, you might also have a lot of ECG's, vitals etc. etc. taken. All new drugs can have adverse effect they don't know about, keep that in mind. This is why I try to reduce the risk by looking at the side effects on previous volunteers. If the side effects are nothing special (nausea, fatigue, dizziness), I will go for it. To participate in trials you only need a passport. You might need a visa to enter the country, that I don't know, but that has nothing to do with the trial. Participating in trials is not considered work, so you are not required to have a work permit. It is voluntary after all! Hope this helps.

Thanks for the comment
I don't think I made it out to be particularly difficult to get to. There is just little to no information on it, and the Lonely Planet makes it out be nearly impossible to get to. I found out for myself that it was in fact rather easy to get to Teweh, and just as easy to get to Malahoi, as I think I indicated in my blog. Thanks for the info on Anoi and Korik, it can be handy for future travellers in that direction.
