Relaxing after a long flight

After squashing myself in a small aircraft seat for hours, I often find myself with a bad crick in my neck and an aching back, despite the aids I have for comfort on a flight. Planes are just an uncomfortable place no matter what you do.

One thing that helps with that is this taking a hot bath or shower when I arrive. Another is this self-massage stick [Note: as an Amazon affiliate, I earn from qualifying purchases]:

Many others are available at different price points, but I like this one as it has many different combinations of angles and rounded edges and pointier edges, so you can reach many different areas of your back and neck easily.
