Thank you to those that sent prayers, postive energy and healing thoughts to my brother. I spoke with him this evening and he sounds better than he has for days. He is going for his cat scan tomorrow and is optimistic about that.
Besides his health problems, he's had such a run of bad luck lately. He did a huge job sailing a boat half-way around Australia which took much longer than expected as the boat kept running into problems, including a period when he was drifting at sea for six days. The owner of the boat still has not paid him the money he promised him. When Geoff got back home, he had his wallet stolen and found that his houseboat (where he lives) had been broken into and most of his special things, like his guitar and a beautiful clock, were stolen. Geoff is a really hard worker and a great guy. It's just not in him to be dishonest in any way and he's having a hard time figuring out why this has happened to him.
Anyway, thanks again. I'll let you know what they find with the cat scan.
