Physically you start going downhill after you turn 18. It is no coincidence that football players retire when they are 30-35. By that time they are already quite far down the hill and the experience they gained can not anymore make up for the physical abilities they lost. Most people do not notice this issue at 30-35 because they never had to run up and down a field for 90 minutes and their body at that age is still perfectly capable for the things they are actually doing. But your physical abilities will continue going downhill and gradually you will have to adjust your activities to match your lower physical abilities. For most people today a significant change in their lifestyle is not needed until they are 55-65, it depends on the person and the lifestyle. So don't worry any more about this birthday than you worried for any other birthday. The change from 39 to 40 is not any greater than that from 38 to 39. On the other hand with every year that passes you get closer and closer to your end, and changing from 30s to 40s is a milestone that reminds you that your end is inevitable and this could affect you psychologically.
