Since a particular post last month, I have managed to significantly reduce my usage of deep-level tube lines. This isn't because I dislike traveling on the Underground (far from it), it is simply to avoid becoming over anxious.
My alternative journey between work and London Marylebone involves a walk from Soho up to Great Portland Street, followed by a bus or sometimes one stop on the tube along to Baker Street.
Morning journeys via this route ('door to door') take about the same time as my old route. Evening journeys take about five minutes longer than was previously the case, but I feel a lot better for it.
