What are some of the simple solutions to varied problems in Fluther that solved a problem?

Like “go for a walk”, “drink water”, and “Take a vitamin” ect. Can we make a list of simple things suggested on Fluther that worked with little effort?

For me when I stopped taking cabs, to and from the grocery store, and walked I felt better and saved more money, because I was giving $5 tips to the taxi drivers.
