How Active Am I Really?

Or, Keeping Myself Honest

One of the reasons I started this blog is because I know how fallible my memory is. I cannot rely on my memory of how active I've been, what I've eaten, or how much I weighed in the past. I've been thinking that I'm pretty content with my fitness level. For a while this spring, I felt strong! This feeling is absolutely real, but it has faded over time. Now, I feel mostly ok, but I know I'm doing so much less than I used to do.

When I retired, I developed a report card for myself.  It tracks a variety of things about my life, from how many steps I take to how many books I read. I don't keep it up rigorously every month, but I actually do keep track of all of the components to be able to bring it up to date whenever I decide to update it. The last time I posted about the report card was about a year ago, where I only posted the comparison to the year before. Because I was still within six months of knee surgery, I gave myself a pass on the activity statistics, which at that point were looking not too bad.

Well, yesterday's comprehensive review of the data revealed a different picture. I looked over a longer period time - basing everything on 2019, when I retired halfway through the year. Pretty much every single way I look at activity has gotten significantly worse, trending further down each year. Sigh. I slice and dice my data, looking at different measurements, averages and peaks and valleys, but it pretty much tells the same story. 

What do I track? Here are my activity measures:

• Average daily calories
• Days with more than 2,200 calories (very active days)
• Average daily steps
• Days with less than 5,000 steps (very inactive days) 
• Stand time in minutes (new in 2023 with Apple)
• Minutes rowing (new in 2023)
• Minutes stationary bike (newly tracked last year after knee surgery)
• Minutes Nordic Track  (new this year)
• Miles walked (while "taking a walk", not incidental distance) 
• Gym workout days (tracked manually)

All but the last of these are from my Apple Watch. When I switched from the Fitbit in 2023, I noticed the calorie counts were substantially different (higher on Apple). I don't really care what exactly the number is or how accurate it is - but I do care that it correctly captures trends up and down. I redefined "active days" to not overstate them with the more generous estimates.

But all of that detail just above can obscure the main fact: I am substantially less active now than I was in recent memory.  I want to tell that story clearly and unambiguously, to convince myself that I need to get off my butt and move! 

So, after bringing the data up to date, digesting the big impact, I took a long walk. Then, I picked up the computer again and made an infographic to show the sad, sad, facts. Remember, I worked in data analysis all of my working life, and using data to tell a story is something I enjoy. So I amused myself quite well, learning how to make a totally new type of graph, and how to present it so it tells my story. So below, here it is:

So what is this?

I simplified my measures to the five comparable measures since 2019 (clockwise from top): Calories, Steps, Active Days, Miles Walked, and Workout Days. I scaled them all relative to 2019, as if that year were perfect. (It wasn't bad.) I display them on a "radar" chart. 2019 forms a perfect pentagon. Each year since then is another pentagon, with this year's data so far in red. We see that calories don't vary much, and neither do gym workout days - in fact, both are slightly better than in 2019. But daily steps and active days are only slightly more than half of what they were back then, and miles walked is less than 25% of what they were. 

Steps, miles, and active days are all increased by getting off my butt more. The more I get up and move, the closer those red corners of the pentagon move towards the 2019 pentagon. 

So it all boils down to this: make the red pentagon as much like the big blue one as possible.
