Put it away and forget it. Buy medical coverage. Even young adults get seriously ill or injured, and the debts could ruin your financial health for years, even decades, to come. If you're not covered at work or by parents, look for a catastrophic policy you can afford. Talk over your finances with your future spouse.
Financial conflicts are a major cause of divorce.
Be honest about your debts. You may want to visit with a financial planner before the big day. A will ensures that your possessions and financial assets, however few they may be at the moment, go where you want them to go if you die unexpectedly young. The living will and the accompanying health-care proxy ensures that you don't get more medical treatment than you want if you're terminally ill or in a permanent coma. The financial power of attorney designates someone of your choosing to take care of your finances in the event you cannot.
