For those of you who are interested and have shown such kindness, an update:

My dad has been put in hospital today. He'd had a really bad night. The visiting nurse thought he'd had a stroke, but when they checked him out, they found his heart just isn't working well. He isn't getting enough oxygen to all his parts, plus the area where they took his toe is blackened...not a good sign. If all goes well tonight, we'll know more in the morning. If, not, then he's had a very good ride. I feel blessed, either way.
