Many long walks start with a breakup or a death. There are many walkers supporting charities for diseases that took a child's life. Some of these people have been walking for years.

People with ties aren't likely to be able to take a long walk. Maybe that's why so many who do take a walk have problems before the walk.

Some start walking after graduating from college and before starting to work. It used to be popular in the 60's and 70's. Others start walking after retirement, especially where a spouse has died.

It would be fun to prepare a questionnaire for those taking long walks, but we'd only find those who write about it.
