SOW Theorem

One long term goal of mine is to qualify for the Boston marathon. BQ is the holy grail for most amateur runners. The qualifying times are fairly challenging and will need some dedicated training effort for someone to have any realistic chance of making it. 

The most important component of this training schedule is the weekly running mileage. One needs to clock close to 80 - 90Km/week to be marathon ready.  Since running is one dimensional, it is also advisable to incorporate some kind of cross training, like swimming and cycling as well. The third component is super important -  strength training. As one gets older, the musculoskeletal system is no longer in a great shape to take the pounding and needs to be reinforced.  Is that all? Unfortunately no. We also need to do throw in stretching and mobility exercises (like Yoga) into the mix. One might argue that we do not necessarily need to spend the same amount of time across all of these, but we do need to spend some time across all these disciplines to improve your chances of BQing.

If one does all of the above, the body will be perpetually in a sore condition and sleep becomes super critical. Without adequate sleep, all of the above is almost useless. In fact, one can never even follow such a rigorous schedule without adequate sleep.

And then, most of us are working professionals. That means we have office commute, late night calls and a bunch of other work related items that keeps us physically and mentally occupied.

So, how does one balance all of this?

People familiar with distributed systems are keenly aware of the CAP theorem. At a high level, it postulates that, of the given 3 variables (Consistency, Availability and Partition tolerance), a distributed storage solution can only provide two. Similar concept exists in economics, called Impossible trinity  So, I propose a similar theorem, called the SOW theorem. This theorem states that, you will have to choose any two of Sleep, Office work and Workout; doing all three is herculean. 

Just to clarify, in the context of the SOW theorem, workout here implies workout of the type required for BQ. Running and strength training for fitness, say for 30-45 minutes a day, which in itself is a laudable commitment, is not representative. Similarly, sleep here implies a minimum of 7 hours. And office is a proper day job (and night calls job, if I may) and not considering a super achieving entrepreneur who only has to work 4 hours a day.

Just like in CAP where partition tolerance is really not a choice, sleep, at least in my opinion, should be non-negotiable. One can play with just the other two. If BQ is the goal, that leaves only one option. You choose a line of work that gives you ample spare time. Or even better, just retire.  What would you, in the same situation - postpone BQ ambitions to after your retirement? Or advance your retirement and go for BQ right now? 

I am still here, pondering over that question...

Decisions

 Life is all about decisions. Should I take this new opportunity or not? Should we relocate to a new location for better job prospects? Should I do the long run or heed to the imaginary injury? Should I join a class to learn something new or am I already stretched too thin? Should I stay away from that delicious cake on the table? Some of these have high impact, life changing in some sense. Some of these do not have that high impact. Some of those affect only you as an individual; others affect your family and friends as well. Some of them are easy, the others pretty hard. However, they have one thing in common - the only way to avoid status quo and move forward is to make those decisions.  All decisions should be consistent with your values, morals and ethics. So, if an option violates your core principles, it is a much easier decision to ignore it and identify the right choice. Such decisions are taken by default and without much cognitive overload. Unfortunately, a lot of d...

You vs You

Once in a while, I go back and read my previous blog posts. More often that not, I feel good reading them. It gives me a peek into what was some of my "top of mind" thoughts at that time. Ideally, if I have been writing often, at least say once a month, this exercise would have been even more useful. Nevertheless, today was one of those days when I revisited my blog. The one that caught my eye today was one of my recent ones - Creation Vs Consumption . As I read that post, I took a step back to see if I have made any progress at all in this dimension over the last year. Coincidentally, that post was written exactly a year back (So much for this being a recent one). And I have to report that the answer is zero; absolutely no progress. I am still consuming way more than what I am producing. This is even after I include my physical activities and the time that I spend doing seemingly productive things at work (which itself is highly questionable) in the productivity list. Which ...

NP hard problem

OK, after being dormant and completely inactive in blogging, I have finally resolved to get back to more active blogging.  It is not that there were any lack of interesting incidents that led to my entering the dormant stage, it was rather a lot of other reasons (read laziness).  Let us see if my mid-year resolution holds for the next half of the year. I will start with a post on one interesting situation I faced a couple of days back. Last weekend, I visited Chennai to attend a family function. And as my wont, I decided to do a long run on Sunday. Chennai, being renowned for the hot and humid place that it is, is not a conducive place for such runs, especially for those who are not used to its weather. So I decided to do an early morning run and left home at around 4:45 AM on a two wheeler. It was here that I realized, in spite of all my years of riding, there has been one problem that I have never managed to solve. That is the problem of handling chasing dogs when drivin...
