I am not convinced with the writer that the tolerance level low with the younger generation as I have seen many elders losing their patience over small and petty matters. It is just the time, the set of mind at that point, the stress level, the environment, the other circumstances that make people impatient and intolerable. There are many elders who can make you relax and convey their thoughts and this is the case with many youngsters. On the other hand, there are many youngsters and elders who lose their cool and throw tantrums. Earlier, we use to have a joint family, everyone around to share, had friendly nature, brotherhood, etc but now, it's just privacy, stress, bossiness, etc and even life is fast compared to olden times. It is the actual, the time, the social media, politics, etc that is infusing anger, division, and restlessness in people that is seen in many situations, and it's not just by youngsters but even elders.
