There are a lot of other threads about this going around.
Note what is going away: Health & Fitness, Food & Drink and Travel.... They are cutting out lightweight, "lifestyle news" aggregation.
In case of Health & Fitness, they now have 2 Apps to replace it. Health Vault and Fitness. Hopefully Fitness will get built out to encompass what is being lost (I think it will) and Health Vault has already proven itself to me as more functional on its own.
