I want to talk about culture - but will wait a bit - after five days in Rio I am still groggy and tired. I have been in my past very judgemental when older people I know quit traveling ... 'you have to go, go, go until you can't'. Now I have to admit that I am beginning to understand. The cost of everything seems way too expensive, the distances from plane to train or taxi seem way too long, the changes, adjustments, delays are almost insurmountable, and it takes too much energy to recover from the trip (not the sightseeing) home. I begin to see that my travel experiences are finite.
