How should you exercise as you get older?

Like nutrition advice, exercise advice seems to change as often as clothing fashion changes. It can be hard to keep up, and easy to get skeptical that any advice is solid. However, if you want to keep up and are not skeptical, read this: How Smart Exercise Keeps You Younger for Longer.

My take, which is a variation of this, is simple: do a range of exercises, from cardio, to strength, to stretching to balancing. A fitness routine that includes all this is better than a fitness routine that just focuses on one or two areas. And any fitness routine is better than no fitness routine.

How long are you going to live? Now you can find out


According to this, you have two very good rules of thumb or models you can use to determine this:

1) The heuristic bi-linear model. We made this by making the best bi-linear model a bit simpler to apply.

It goes:

If you’re under 85, your life expectancy is 72 minus 80% of your age.

Otherwise it’s 22 minus 20% of your age

2) The 50-15-5 model. This one asks you to remember some key values and then to interpolate between those values. It goes:

The life expectancies of 30, 70, 90 and 110 year olds are about 50, 15, 5, and 0.
