At any point in life I keep in touch regularly with about 40-50 people. Most of them are from outside work. Because "but you spend 8 hours with them every day" is not true for most people. I now work with completely different people than I those I worked 3-4-10 years ago. I have friendships significantly longer than that, and I didn't have to work with them side by side all this time.
