Also, if you're going to keep the wallet on you, at least once a year take a couple of minutes to photocopy everything you have in there - as in all likelihood you'll forget some things.
Ditto - for your house - not a bad idea to take the iphone and walk through the house recording everything. One of my nieces just had a home burglary. She kept all of her jewelry in two convenient to steal jewelry boxes - things from her grandmother and parents - irreplaceable. She also happened to have a more cash than one would normally have at home because she'd taken it on a trip. I won't say how much except that I have never carried that much cash on any trip. Of course, they took Coach purses and other high end portable items. Two weeks before a tree collapsed on her car - so she's on a roll for bad luck.
