5) It seems that you have relatives and friends but not children. Without an heir, we are without true fall back. Plan accordingly. Treat your relatives' and friends' children nicely. When we are in our 80s and 90s, they could be the ones visiting us and coordinating our care.
6) Be open minded on getting married again. There is nothing wrong with that and there is fine meeting people over internet.
7) As to the income side, be self-employed. I will provide several ideas.
a) Go into something relating to food. Plant vegetables and sell them. Prepare food for restaurant or retail store. Oh, if you are healthy, you may be able to find jobs in this industry. Less resume needed. When economy is not good, such as in the U.S., we have only three industries left, health care, food, and computer.
b) If you wrote and prepared manuscripts before, maybe you can publish them, e.g., using Amazon.com. They provide all costs and services and let the author keep 75%. But in general, their price is very low. Children's book, cook book, etc. Look into Amazon.com's publication. They are not that difficult. You can start with smaller and short ones. Some of the publications are like just several, less than 100 pages. If you can write novels, you would be blessed. One good thing about your situation is that you don't have a current, urgent condition.
c) Use internet to contact companies in China, etc. or Canada to arrange travel groups in both ways. You don't have to organize large groups. A small group may give you some commission and you can start into the industry.
d) Consult with Canada's chamber of commerce and New Zealand's organizations in the similar capacity to ask for ideas. New Zealand is a beautiful place and not many people know about it. This country has a lot to export.
Remember when you are going into business activities, do not put up your own money. This is very important.
Part III will come soon.
