I have always been proud of my bladder control. I don't want my middle-aged friends to go to the bathroom frequently. The motorway pitstops are for pee. It wasn't me. I didn't say I'd better just pop to the loo. No need, you know what I mean. I spent hours drumming in pubs, waiting for my friends to come back. Poor souls are aging faster than me.

It's sheer arrogance. A few weeks ago, I read that a man my age and weight should be drinking 3.6 liters of water a day. My pride in my bladder has been removed since I have complied with this guidance. I wasn't putting anything in it, so I was able to control it.

It takes a lot of commitment to get rid of that amount of water. I have always started the day with a small glass of water, apart from the odd tea or coffee that would be about it until teatime. It's not any more. The app on my watch is telling me to drink more. I tend to go great guns until lunchtime when I lose focus and the target gets closer. The input side of things isn't as challenging as the output side. I run to the toilet all the time. Any distance between me and a toilet needs to be carefully planned.

How do you get a properly hydrated person to do something? How do they get around? I don't know what it is. I want to know the hydration levels of successful people. They are as low as in August. The lavatories at the G20 are not being used. There is no way those world leaders are consuming that much water. They would always be rushing out of the sessions to relieve themselves.

I don't think hydration has been in a good way for me. I want my life back, even though the skin is glowing.
