Hello friend
The great impact if strictness could be seen in children as you stressed they tend to have a sense of harshness when they are with their friends and also stubborness is the order of the day, the bright side is that they grow up to know how to use their time well and also know how to be disciplined in the world of today too. Emotional black mail could cause high blood pressure as you stressed and other health problems. Success in the challenge my dear friend
