How should I do?

Just wondering what I should do when I die.. Do I want to be cremated? Actually not sure leh.. Hate incineration. Contemplating water burial.. Should I opt for that? Don't think I like an actual burial lah.. My body will simply rot & disintegrate to ashes anywayzzz.. Once I decide, I must go tell someone, just in case :) Sigh! Think I've been sighing a wee bit too much of late..
