Much like having a living will, you should make decisions regarding burial or cremation ahead of time. If you would prefer cremation, there are several aspects to consider.
If you have friends and family, you might want to know how they feel about cremation. Ultimately, you have the final decision, but you may want to make family members feel better about the idea. If you are indecisive, having input from people who care about you might make your decision easier.
