I not only live alone, but in an isolated flat in a foreign country! I have listed all my pensions, bank account details, names and numbers of family, etc. plus a copy of my will, and given the file to my Swiss friend, who could deal with the French authorities for my daughters. She would also help if I had to go into hospital - she lives about 120 miles away from me, but I know she would come if I needed her. Things were much simpler before my daughter emigrated to New Zealand but she and Odile are Facebook friends and often chat to each other behind my back! My daughter in the UK would not be able to cope at all.
I don't really need a will if I die in France as inheritance is strictly governed by the 'Code Napoleon' and you cannot disinherit your children.
I have left explicit instructions for disposal of my body - donate everything useful, try to give remainder for research, no religious service, everything to be done as cheaply as possible, no expense of repatriation.
I don't have any underarm hair - it just stopped growing about ten years ago, and my doctor just shrugged and said 'hormones'. I don't wear make up of any kind, as I really don't care about my appearance as long as I am clean and tidy.
I used to be named as executor in both my daughters' wills and also as legal guardian of their infant children but we jointly decided when I turned 70 that it would be unrealistic not to have younger people, so now the adult GC are named as guardians for the minors, if both parents should die.
