New lease on life

Just read about a guy that got a new lease on life. For the longest time I thought that saying was a new "leash" on life. The new leash idea evokes a picture of lassoing life with a leash and reeling it back in. I like the lease thing better. It reinforces the idea that we are tenants on the planet for a temporary term. Our lease will end at a certain time, but then occasionally we get an unexpected windfall, an option to extend. Let's all enjoy our current leases to the fullest!
