Worried

I am worried. On Friday I will fly to London, UK, and I don't know what is going to wait for me up there. According to experienced people the biggest problem is food, but I am not going to stay long, I guess I can manage for 2 days. Water is a more serious problem, but I guess I can always distill some Thymes water for drinking - or switch completely to beer (which in the past was used as water to prevent deseases caused by pollution). I will bring some battery powered devices, and a manual recharger, even though I am not sure what I can do with those in such a country. I feel like Cristoforo Colombo, travelling towards the unknown and the "uncivilized". Exciting, but dangerous feeling. I should have listened to the wise advices and never made those tickets.
