Retirement and cognitive decline

A close friend of my late grandfather passed way recently. The pattern of his decline prior to his death, however, was unerringly similar.

My grandfather, till the age of 67, was admired for his relative youth. He went for a swim everyday at the community pool near our home, ran a cost accounting business with a partner, read a lot, and was active. At 67, however, he decided (with his partner) to shut down their business and “retire.”

Every year, for the next ten years, he aged at the rate of three years for every one. The average amount of television he watched per day went up during this period from one hour to ten hours. His physical decline during this period was the hardest for us to stomach. He went from walking and swimming a lot to barely being able to move. His last years were tough on him.

The fable of the frog in boiling water may not be real but its implications for human behavior are definitely true. We were caught unawares by this gradual transformation. And, before we realized something was very wrong, it was too late.

This close friend’s story was similar – his cognitive decline after “retirement” was swift.

The world’s population is ageing. Combine that with advances in medicine and we have a generation that is also going to live longer than any other. As we all learn to deal with our ageing grandparents, parents, and eventually, ourselves, it is worth remembering that the enemy is cognitive decline. There is a lot of truth the phrase “its all in the mind.” Physical decline follows cognitive decline (while this was our observation, it may be that there’s a feedback loop that accelerates both).

My lesson from this experience was – Don’t allow your loved ones to “retire.” Find ways to keep them mentally engaged and away from excessive television.

Death is a natural part of the life experience – but, severe cognitive and physical decline needn’t be.

Age and wisdom – correlation and causality

If you ever want to understand what Economists describe as the “Identification error” – mistaking correlation for causality – just take a look at the relationship between age and wisdom.

There is undoubtedly some loose correlation between age and wisdom. Take a random 60 year old and a random 20 year old and it is likely that the 60 year old is wiser. While there exists this loose correlation, age and wisdom do not have a causal relationship. Or, to put it differently, growing older doesn’t automatically make you wiser.

Wisdom is defined as the quality of having experience, knowledge and good judgment. I would simplify this further as “the quality of having knowledge and good judgment.” This is because good judgement comes from experience, which, in turn, comes from bad judgment. This explains the loose correlation between age and wisdom. As we age, we tend to have more experiences and these experiences could improve our judgment.

To understand why it is hard, it is helpful to understand what I think are the pre-requisites or causes of wisdom –
An array of diverse experiences. If you have done the exact same job for 20 years, you have, in some ways, lived through the same year 20 times. The experience gained from such an experience is very narrow.
Reflection and assimilation of your learnings from these experiences. Even if you have had diverse experiences, there is no guarantee you’ve learned from them. Learning requires a commitment to reflection and assimilation.

It is hard enough to push yourself to find diverse experiences. And, it is exponentially harder to then extract the depth of insight from your experiences. That is why wisdom isn’t common and why it is flawed thinking to assume that age leads to wisdom.

It isn’t the years in your life that count. It is the life in those years.

A few thoughts on age

1. The concept of age is largely a mental construct. Yes, our body does change over time . However, we often exaggerate changes to suit societal norms.

2. Societies  (especially more hierarchical ones) often attach many expectations to age. There are certain expectations on how to behave and how to live. The reason for this is that age is a great tool for enforcing mindless hierarchy. “I am older than you. So, I know better.”

3. The truth, however, is that respecting someone because they are old is completely arbitrary. It assumes wisdom and that’s a flawed assumption. Wisdom doesn’t come with age. It comes with maturity, openness and self awareness. While the probability that an older person may possess these are higher, I’m not sure it is much higher because openness tends to decrease with age. A friend of mine feels respect is one of the most misused words in the English language – I can see why.

4. For illustration of the above ideas – think of five 80+ year olds you know. I’m sure you can name a couple who act and move about like they’ve reached the end of their lives while there are others who still possess extraordinary youthful exuberance (a certain Warren Buffett comes to mind). Think also about a few more older folk you know – would you consider all of them mature, open, self-aware, and wise?

5. Ageing has a lot to do with mental inactivity. I’ve sadly learnt this from seeing this with my grandfather. Until 10 years ago, my grandfather was known to be a 68 year old man with tremendous energy and youth. However, after his decision to stop working, we’ve watched him age at 3 mental years to the rate of 1 physical year. The difference is profound.

6. Television plays a very negative role in an older person’s ageing process. You can almost always be sure that their mental age is linked to the amount of television they watch as the television encourages a permanently vegetative state. Video games are better – perhaps theirs an opportunity in having older folk play video games?

7. If age is largely a mental construct, should we bother about the right age to do this and that? Only to a point. There are some things that make more sense at some ages – like university degrees while we’re young so we’re not a burden to our parents and becoming parents while being relatively young for biological clock reasons. But, beyond that, there is no right age for anything. It is all about being ready. So, the next time you hear about something making sense because you are at the “right age,” question it.

8. The biggest mistake adults make is they forget what it is to be kids (hat tip to J K Rowling). The toughest part about growing up is making sure we mature enough to not be childish but continue to be childlike. This means retaining an insatiable curiosity and a willingness to be open to any possibility that might present itself to us.

9. Age, wisdom and happiness are a wonderful combination. But, as Prof Mihaly Csikszentmihalyi says, they don’t come as guarantees on our birth certificate. We need to keep learning, we need to keep working hard, and we need to be persistent in the face of our attempts failing. None of this gets easier with age. In fact, I’d even argue it only gets tougher. So, it is up to us to ensure we stay mentally young while growing wiser through increased reflection and self awareness at the same time. It is hard work. But, hopefully, we’ve learnt by now that embracing hard work is the only way forward.

10. The best part? If we work hard enough on it – we don’t just get older, we get much better. Think of what a small daily improvement will mean 25,000 mornings later..
