I have four, one to go shopping in person with, one by the computer for online shopping and the other two mostly in case anything goes wrong (like today) or someone won't take Amex, as is quite common. One of them doesn't charge commission for purchases abroad, which is useful.
My gum had better stop bleeding tonight, or else. It's been okay today, so I am hopeful.
That just leaves my back ... it froze in bed last night, I spent ages inching towards the edge so I could get up, and the writhing set off cramp in my foot. Came out of nowhere, and I hope it was a one-off.
