How is your fitness? Your strength and conditioning? It is critical that you are strong and in condition. If you are reading this, you are a human, and your mind and body deserve this. For most people, 5 days of exercise per week is recommended. This will vary on your activity level. An office worker will need to exercise more than a construction worker. I know that 3 days of CrossFit plus two days of other exercise (long walks, easy runs, hikes, sports activities) per week will build your strength and conditioning to a nice level. Also good eating is crucial. Both activity and eating right need to be done consistently over time. Your long term health is the key factor here.
