As you read through the post so far you will see several trends as well as several things people disagree on. Some are very opinionated about things like cotton clothing without taking into account the climate of the others on this worldwide forum.
What you need to do is learn the principles of dressing to survive for your weather and time of year.
The obvious benefits of cotton during the summertime in hot climes are totally negated in cold climes. Yes cotton is much better around fire than the poly whatever flavor of the month fabric, but so is leather and wool for winter dress. Each like everything else in this world has its advantages played against its disadvantages.
You seem to be in an awful hurry to catch up with many of us gadget wise with out realizing it’s about life style and a way of thinking not gadgets. Many on this forum live this day-to-day and have for years. Many of us have lived though “interesting” times and know its just a matter of time before more “interesting” things happen to us so we do what needs to be done ahead of time to live to see the next set of “interesting” developments.
This is not something you can throw money at to make happen it is something you learn about over a lifetime.
I have no clue if you are doing research here or are just a little worried about what you see happening around you. Either way you need to slow down take a deep breath a feel the rhythm of this forum, learn some of its history by reading or at least scanning the old postings.
You may think people here are acting a little tribal but that is to be expected we are use to the ebb and flow of this forum and are not use to you yet. If you are a kindred spirit you will fit in it just take time!
