As I write this, I feel euphoric. I ve just emerged from the sea, off the Suffolk coast at Aldeburgh. Yes, it s May, but the North Sea s never as cold as you think it s going to be – or, I admit, as warm. Nevertheless, from April to October you can easily immerse yourself in it for minutes on end, without swearing. You don t have to breaststroke the length of the beach to experience the natural high. This morning I didn t swim anywhere. I simply plunged in, did a couple of hundred bicycle kicks and let the current take me as far as the north lookout tower, where I got out and strolled back down the beach to where I d left my clothes. Is that swimming or cheating? Who cares? All I know is, it left me with a huge, renewed appetite for life, love, beauty, truth and, above all, scrambled eggs.
