Personally, I think one of the greatest gift any adult can do for their loved ones is plan their memorial service, regardless of his/her age. I think it should be part of the info/checklist package that comes when a person fills out a will. Think about it: people leave a list of where they want their belongings to go - why not leave information regarding how you want to be celebrated?
If something happened to me tomorrow (God forbid), my husband knows that in a folder in our file cabinet, there's information as to what I want in regards to a memorial service, where I'd prefer to be buried, how, etc. It's not because I'm a control-freak, but we've seen how friends and family struggled, and spent a LOT of money, on decisions when a loved one had passed. My husband's got a folder in there, too. I'm not yet 29 years old, he's 31. We're both healthy and determined to live long, full lives.
But just in case ....
