I either eat alone browsing the news - keeping up with politics, football (soccer for Americans) and cricket, as a young family means I cannot do this at home, or nip out for a swim, gym session or game of squash (my preference).

Maybe I might go a little over the hour for sporting purposes but I think it is well worth an extra half hour in the evening to avoid being sedentary all day. Though I do cycle to work and often go to the gym in the morning too. I think my employer gets good value for me being healthy and fit - the time spent really recharges the mind IMO - though maybe it is just me!
