System2 is a CPU during a trip, with a limited resource i.e. attention. A constant stressor, distraction… is Physical cash.

rules ranked by Priority

1. leave all local currencies behind. See “coins” below.
2. keep close to “skin”, beneath clothing
3. keep all the bank notes to 1-2 places only, to reduce “system2 load”
   1. eg belt and stretchyPouch
   2. eg wallet
   3. ^^ If below $1000 then wallet-alone is enough
4. avoid re-arrange the pockets (belt is embarrassingly clumsy to open 🙂
   1. OK to mix currencies in one place
   2. OK to keep “unusable” cash in wallet. I seldom take out any currency en-route

— coins .. minimize coins carried. They become a heavy and worth-less burden. Consider “donating” to a cleaner.
