I try not to book that short a connection but when it happens, either by a late incoming or a schedule change, I have made it every time.

However, if it turns up less than 35 minutes, I will figure out something else. But then again, I am usually going to a destination where there is another flight in an hour (and another an hour after that). So there is no nervousness involved as my inbound flight lingers in the air longer than expected.
