Health

Ageing is not separate from Alzheimer's or heart disease. The leading causes of those diseases is the ageing process, which we can now control. Based on what we're doing in the lab, we know that if you turn the clock back, those diseases go away- that's a revolution. We've been working on a band aid system trying to fix the diseases that are already there, while ignoring the main cause.

Ageing is malleable, we can control it. 20% of our health in old-age is due to genetic factors, and the rest is due to our lifestyle. We can measure this clock. It's literally measuring chemicals in our own DNA. Here's the good news…. That number can be changed. If you smoke, if you don't exercise, if you eat lots of fatty foods, that number will accelerate and if you do the right things, perhaps even take some medicines, you can slow that number down – even reverse it.

Emotions are perception, but perception of the body itself. You see something scary like a bear, that triggers all kinds of physiological changes in your body. Your heart rate increases, your breath quickens, and the perception of those changes is the emotion. Emotion is another kind of controlled hallucination but geared to the interior of the body rather than the outside world.

You need one strong relationship in your life to remain sane. You need a relationship that doesn't depend on digital transmission! You need somebody who you understand deeply, who you can talk to directly, who can give you a reality check when everything coming through your computer and phone is bewildering.

We can become resilient however, and learn to have peace of mind, even when we experience traumatic events. We can learn to have stable peace of mind... happiness? Maybe not. It's unhelpful to say to someone, 'do these 10 things to be happy' – there are things you can do to get peace of mind, increase your probability of happiness, and your probability of having successful relationships.

The reason we can't be happy, and not worry about other people's opinions, is that we're sharing our minds with a machine that does worry about other people's opinions and which does get anxious. If we can dissociate from that, and learn to manage it, it can improve our lives significantly.

I define robustness as saying that we're fit for purpose, 'I'm sat in my house in the morning, I'm in a great place, I'm robust and ready to face the world and deal with any emotions my brain throws up' It's having a plan and being ready. Once I open the door and life happens to me, I've got to say robust, that's resilience. Robustness is being in a good place and having a plan, resilience is being able to implement that plan and stay in a good place.

Words like mistake, error and complication are not helpful. They carry visceral, emotive, weight which hampers learning and thus obscures what you may be able to take from an event. Over the past 20 years, we've moved away from that terminology towards the language of adverse events.

With technology, we're creating a lot more hammers – and with more hammers, we're able to find more nails. The question is whether those hammers are being made for the right purposes, and whether they will serve the right purpose. I often worry that when we talk about health-tech – it almost seems that in certain areas the tech is taking over the health.

You need clarity of vision and purpose. You need to know the reason you're there at that surgical table with a knife in your hand. You have to be clear that you are using these sophisticated tools (tools which can cause a lot of harm) to fundamentally and primarily help that entity, that child in front of you. That mindset provides the energy and focus needed to carry out the task.

Surgery, like many other disciplines, is primarily about facts, your relationship with the facts, how you manage, handle, interpret and use those facts. This is something we all begin to do very early in life, in our childhood. We look at information coming in from the external world, determine what is useful, determine how we understand it, build a fuller picture and effect change. A surgical mindset is very much that.

I knew I could still fight, and some of the people close to me said, 'not with one eye you can't' so I continued anyway... I lied, I cheated and scammed the system... I did whatever I could. It was highly stressful, but I believed in myself.

From a rather dispassionate, clinical perspective, and if you remove the awful consequences that people experience when something does go wrong, you can see conditions like synesthesia as nature's experiments. We can learn a lot about the underlying functioning of our nervous system.

Smell is an outlier. The way smell works is that the brain essentially sent out a little tentacle into the world, those nerve fibres are the only contact between the central nervous system and the external world. This is the point at which there is no barrier between the brain and the outside world.

We got to the point where, we are not on our grandparents' planet anymore. Meat has become less healthy for us – it's too available. There are too many calories, too much saturated fat. Animals are no longer 'free-rangy', they are growing in very tight confined conditions.

My greatest fear is that we have learnt nothing. Individually, we have learnt that the longer your population lives healthy, the better off your economy will be.
