Firstly there is the reasoning that my family will get it all if I die, so they can sort out the paperwork when I am gone. Eventually this might be true, but these people will leave their families with a lot of sorting out to do, more trips to solicitors or probate specialists, and the added grief that they have to sort out what could have been easily sorted earlier.
Secondly, there is the excuse that they do not care where the money goes. Again, this is fine, but somebody has to sort everything out. Your family will have more to do again. Of course, if you don't have a family, or any living relatives, then you must be happy for the state to have everything? Would you rather leave it all to a good cause instead? If so there are charities who can help for free, where they are the beneficiaries.
Thirdly, there are the other excuses including 'I don't have anything to leave', 'I am too young', 'I don't trust solicitors', or 'I can't afford one'. Let me reassure you that you are never too young (well, once you are 18!), it's not about what you leave, it is to ensure things get sorted more quickly, if you don't trust a solicitor, see a willwriter! Of course, if you can't afford one, you may be able to get a free will. Please contact me for more details.
The bottom line is, get a will - there is no point thinking there is safety in numbers - i.e. 6 out of 7.
