This idea requires a fair amount of planning and preparation, but you will end up with one of the most magical birthday parties ever for anyone who is turning 40. Take a look back at their life so far by creating a ‘This is your life’ themed affair, with a big red book filled with memories and photos. Of course, introducing special friends and family one by one will come as a shock to the person turning 40, but it really will make them feel like an incredibly special VIP!
