Just think it is possible to travel through time - like Claire Beauchamp in Outlander - and arriving someplace 200 years back.
You'd find yourself in 1815, right at the time of the Battle of Waterloo where Napoleon was finally defeated.
What would you take along to such times, if you could fill this one rucksack to bring along when you step through the stones?
For myself, I think I'd carry the following:
* some bars of soap
* enough toothpaste to last a while
* toothbrushes too
* dental floss
* some sets of clean underwear (bras and undies)
* a pair of soft slippers
And of course I would leave wearing sturdy walking boots (normally I can wear shoes or boots for over 5 or 6 years).
What would you take?
