I try not to go into Portland, OR too often, but when I do I am usually stuck in traffic, 4 lanes each direction. I think about all the pistons and valves (springs & valve guides included)going up & down, cams & alternators turning in each vehicle. I used to just keep track of the vehicles going in the opposite direction but recently added all those going in the same direction.
Is this motion of the Islands, plates, mantels & hotspots something I need to pay more attention to? I have space available.
Smile ... Depends on the state of your nerves and supply of "Depends(tm)" I guess. Portland is somewhat close to Mount Hood if I recall correctly and the USGS maintains an web page monitoring the condition of this active volcano. If it is important enough for local school kids to have volcano evacuation drills and active seismic monitoring - do you need to pay attention? Do you have the time to pay attention to everything that people tell you to worry about? I don't know about you, but I overloaded my worry file about 50 years ago and it is just getting worse all of the time!
