After a visit to the cath lab, I've gotten crazy serious about my health and have been listening to Dr. Peter Attia's podcasts after reading his book "Outlive". Really, really good material. He rides a Pinarello instead of a Colnago, but I can probably adjust to that. One of the data points he discussed is recovering from broken hips at our age. They are devastating to "all cause mortality" due to the loss of muscle mass and bone density from the bedrest. For example, at our age, it takes 6 months to regain the same fitness level prior to one week of bedrest.
