I buy mine to remember the sacrifice and horror (not for me personally thank god) although my granddad did get a Haig house before eventually going off to be a Chelsea pensioner. As for the young lads in modern conflicts having a choice .... I don't really think so. So many kids leave school with very few prospects and very little understanding of history - you can end up catching a bullet thousands of miles from home before you know what you signed up to.
I used to like the white poppies you could buy as an alternative.
