I love packing my bag even if it's for a few days (which I do quite often). And yes, absolutely agree that age has nothing to do with the travel bug. Actually scientist believe that it's part of our genes.
This is an extract of a study:
"Studies over the years have proven a link between an excess of dopamine in the brain and a tendency to engage in impulsive and dangerous behaviors. This surplus dopamine has also been associated with a specific variant of the DRD4 gene, which codes for a single type of dopamine receptor called the 7R+ allele. While this genetic variation has previously been tied to issues like gambling and addiction, it can also explain a more benign compulsion, the urge to travel."
Very interesting, I will tell my mother that see never understand why I always want to leave again. My parent dont travel that much, maybe the last few years a little, but they love "home"
But now I can blame a study! love it
