Start with your decade

In your 40s.

The slope has started. You probably can't feel it, which is exactly why this is the decade to measure.

Where you are on the curve

Muscle and bone are slowly declining. Blood pressure, blood sugar and weight tend to creep up a little each year. None of it hurts. All of it adds up.

Accept it: Your close-up vision will start to go. Accept it. That isn't the one to worry about.

Your likely weakest links

Blood pressure

The most common silent climb of this decade.

Blood sugar

Weight around the middle and a rising A1c often show up here.

Sleep

Stress, and for many women, perimenopause.

What to fill first

Keep strength training. It's what slows muscle loss. Watch your waist more than your weight. Guard your sleep. If work pushed your friends off the calendar, put one back.

At-home checks

Blood pressure

Home cuff, seated, after five minutes of rest.

Grip strength

A hand grip meter.

5× sit-to-stand

Five times, arms crossed. Time it.

Balance

One leg, eyes open. Count the seconds.

Weight & waist

Waist measured at the belly button.

Check once a year, same time each year, so you can see the trend.
