It's one of those things i've found younger people say 18-20yr olds don't generally get.. and it's so so vital!
ZF that's a really good point as when i was 18yo i was nearly NOT going to get Ambo membership thinking i'm young as long as i don't have a car accident i will be alright but thankfully my BF at the time who had membership talked me into joining as he pointed out as i had no family to financially help me if i did get footed with a big bill i would then be on my own at 18yo+ to pay it ... so yep paid my ambulance membership at 18yo and can you believe back then it was only $17 for a single !!
