In more practical terms, you can always prepare for your passing. If you have a lot of possessions or you want to make things easier on your surviving friends and loved ones, look into writing up a will; someone that passes away without a will is considered to be intestate. Avoiding intestate status means that you will be saving those people a world of trouble in dealing with probate courts in order to appoint an executor to your estate. The most basic stance to have on human mortality is to live healthily; exercise regularly, get into a regular sleep schedule, follow the proper nutrition guidelines in your eating habits, etc. Death comes to all, but you can certainly slow its arrival.
