I agree, it is continuing process, or it should be. Without that there is no too much sense of anything. While I am getting older, my physical abilities going down, it is normal, but definitely I know much more now then I knew 10 years ago.
For me it is about family and group, so I ll just pass on knowledge, just like I learned from older then me. I ll try to give my best in fields that I can give most.
It is life.
