The human race, as a whole, is living longer these days than any previous generation, which is why Rob Carrick, of the Globe Investor, has devised a new list of financial realities for all future generations to keep in mind as they grow older...and older.

Our thinking about personal finance needs to catch up with our increasing lifespans.

Making it to your late 80s is now routine. New data from the Canadian Institute of Actuaries shows a 60-year-old man is projected to live another 27.3 years, which is 2.9 years more than previous estimates; the average woman of 60 has another 29.4 years—an increase of 2.7 years. Here are five financial realities of living longer:

1. Young adults may have to choose between a house and retirement

Today's college and university graduates are savvy enough about money to know they need to start saving as soon as they're able. Between student loans and a weak job market for young adults, that's not easy. But there's another issue that hasn't been much talked about: Should young people use their savings for the down payment on a home, or for retirement?

A typical reply would be that they should save for a house, then retirement. But with houses as expensive as they are now, there may not be much money for tax-free savings accounts and registered retirement savings plans after paying household expenses.

Future pay raises won't solve this problem. Today's home buyers will need their salary increases to cover higher mortgage costs once interest rates rise. Question for further study: Will renters enjoy a better retirement in the decades ahead than home owners?

2. The best careers offer a glide path into retirement

In a world where it's common to live to age 90, it will be common for people hitting the normal retirement age to work after stepping away from full-time employment. It may be the need to stay engaged that prompts people to seek work, or it could be insufficient retirement savings. Either way, they'll be seeking work or consulting opportunities that allow flexible hours and decent pay.

Retirement can be a time to reinvent yourself, but let's recognize that it will take years to get your new career going. The quickest way to find work in retirement is to draw upon your contacts at your old job or in your profession. Everyone 50 and older should be thinking about this.

3. The old “100 minus your age” formula for setting an allocation to stocks is dead

If you're 50, this formula would dictate that you have 50% of your investment portfolio in stocks and 50% in bonds. This may not be aggressive enough to build enough retirement savings to last 25 or 30 years after retiring at 65.

A more effective way to divide up your portfolio would be to subtract your age from 110 to get your allocation to stocks. A case can even be made for using 120. Either way, many investors will have to find a way to get more comfortable with the stock market. Relying on bonds and guaranteed investment deposits likely won't get them where they need to go.

4. This is the dawning of the age of annuities

Sold by life insurance companies, annuities offer a lifelong stream of income. Money comes every month until you die, regardless of what the markets are doing. And yet, too many people give no serious thought to adding annuities to their mix of retirement investments.

Annuities may not produce the best possible return on your invested dollars, but they compensate with their zero-stress ownership experience. What a perfect complement to your more aggressive investment portfolio.

The insurance business seems ambivalent about annuities, maybe because agents make more money selling segregated funds and guaranteed minimum withdrawal products. But both individuals and advisors should give annuities more thought. That's especially true for people in families where there's a history of long lifespans.

5. You have no choice but to save more

Living longer puts a strain on your retirement savings that you can address in advance by working longer (see point No. 2), investing more aggressively (point No. 3), lowering your expectations for a retirement lifestyle or saving more. Plan to do some or all of these, but realize that saving more is the option that gives you the most freedom to do as you please.

Another reason to save more is that the government and employer role in paying for retirement is declining. That's not to say we won't get the payouts we expect, although you can't rule out anything. More likely are takeaways along the lines of what the federal government did in the 2012 budget to contain rising Old Age Security costs. Starting in 2023, the age at which OAS benefits begin starts to rise gradually to 67 from 65.
