Aging

As we accumulate grey hair, we should also get multiple interests/hobbies/likings/things we love to do/engagements/pastimes/fancy amusements to make life more interesting, or else couch sitting or armchair thinking will surely prepone death and dullness. If you are passionate about music/poetry/movies/old coins/stamps/documentaries/books or anything else of that sort by 60-70 and do something about them then surely life will have more vigor and passion.
Else we are lost in the gossip of the neighborhood, meaningless political debates, and involved way too much in the lives of grandkids.
