Before life corners you with a bent back, how about rounding off it's rough edges with your smooth understanding? Remember, maturity is a stage and not an age. It just does not come with time and grey hair, not unless you work towards it.
In Graceful Aging, Swami Tejomayananda, makes you see the senility of seniority with his characteristic wit. He makes you sit up and say "O,I say this or do this all the time!" He then gently pushes the 'walking stick' of a higher perspective'. so that you don't get stuck in twilight traffic, but move on with firm steps and fresh breaths!
The cartoons enable you to laugh at yourself.
