7- How to find people in the travel, or how to know people in the travel.

1. Yes, but it is likely to be expensive.
2. You make sure that you take the appropriate clothing, or buy it when you arrive.
3. Do research online before you travel.
4. You need to check before thinking of booking a trip to those countries whether you need a visa or not (that goes for anywhere you travel to abroad).
5. You make sure that it is locked before you leave. You could put some lamps on timers to make it look as if someone is in. You could ask a neighbour to keep an eye out for you.
6. You make sure that you have travel insurance and if you are on medication, make sure that you take enough with you for the trip.
7. I don't understand the question.
8. Not good - unless noise and other people walking around don't bother you.

Your back…

1. Of course
2. Don't pack your Parka
3. What do you want Cheap or Good. You won't get both
4. Walk
5. Of course I have people watching it. I have 24/7 video surveillance with armed response. As soon as even a leaf hits the ground 2 1000 Watt flood lights illuminate the area and it is sprayed with pepper spray.
6. Throw up
7. In the Travel What?
8. Hard. Just remember to leave your wallet on the floor next to you so when you the pick pockets come around they won't wake you up.

1. Yes.
2. Pack light.
3. Anything that is called Motel is a cheap hotel. Anything that has international names, like 4seasons, Holiday inn are opposite of cheap.
4. Fun, interesting, since when is India poor?
5. Lock on front doors and don't post about your trip on social media so people wouldn't know that house is empty for taking.
6. Buy a trip health insurance so that if something happens, they would cover the expenses in the hospital.
7. Same way you do home, by saying Hi.
8. Cold and very uncomfortable.

1) Yes. Price it at their web site online first.
2) Pack for where you are traveling. Wear a sweater rather than a big coat. Try to avoid being outside in getting to and from the airport. Cold to hot is much easier than hot to cold. Some thin (skinny) people have more difficulty in both directions.
3) Booking sites like Booking.com and Trivago.com. I find trivago great at searching many sites, but bad at stating extra fees at the hotels. Possibly Hotels.com and Expedia.com. Tripadvisor.com and Oyster.com can be useful if the hotel is listed there.
4) I have seen plenty of poor people here in Las Vegas at street corners and in a visit to China. I really have no desire to review poverty in my travels.
5) Best to have a relative or neighbor check up on your home. But, considering in daily life it is empty often, it's all about trust. You can possibly inform local law enforcement if you think they are trustworthy.
6) Some people buy health insurance for travel. Some do not and take their chances and pay as needed. Some coverage from domestic insurance may exist if you check your policy. Some credit cards have emergency benefits if the card is used in travel. Life isn't perfect.
7) In general in travel, some people pay for tours and tour guides and other travel independently. Language can be helpful, such that they speak yours or you speak theirs. People are people everywhere, and if you travel across your own city, you don't know anywhere there either.
8) A few airports have lounge chairs, and sometimes need to be located. Airports are not meant for extended sleeping. Many airports have nearby motels and some have sleeping cubicles you can rent. People prefer short change of plane times and even better is non-stop. Sometimes you travel to another city up to a couple of hours away or so just to get a non-stop flight. Consider an airport is a public place and easier to sleep on the plane than at an airport.

Overall, I very much enjoy traveling to other places and experiencing new things and a change of weather can be refreshing and enjoyable. Yes, it is not a perfect thing to get there and properly plan a trip. Some people have difficulty being alone without a support structure of people as friends and family. Some people worry about everything. I see all of life as an adventure. We were given a gift of life to enjoy it. One of the ways I enjoy life is traveling to see and do things. I live in Las Vegas now. It is a fine adult playground, but really hot and dry in the summer that starts in May and continues into September.

Yes, you can buy a ticket at the airport, but please don't. The airlines barely have enough people working the counter to check people and their bags in for a flight. Dealing with some idiot that wants to buy a ticket while a few hundred people are in line trying to check their bags slows the entire process down. Some airports have kiosks to buy tickets, though.
As for the rest, please ask multiple questions separately.
