The advantages of such a move are enormous: it would ease congested traffic and make the roads safer, improve ecology, and above all - improve people's health.
Cannabis is gradually getting legalized in various parts of the world. It's a positive direction, and it should include as many countries as possible. I'm in favor of legalization of this plant which is said to have the potential of easing the suffering of the sick (cancer/ parkinson patients and others). They say, it is not addictive like alcohol, and not harmful like smoking.
Egypt's president, El-Sisi, has recently launched a rhetorical 'attack' on the overweight in his country and told egyptians they should take better care of themselves. Opposition to his words is loud, invoking poverty, junk food, faulty health care, and the other usual slogans; but his clear voice on the matter is a start, a good one, even though he might do nothing practical about it.
It seems El-Sisi is the right guy in the right place who might bring about significant changes in his country (including the issues of obesity and the alarming birth rate), setting an example to the other countries in his continent.
Scientific researches of the last couple of years might give us, in 2019, a clue as to the workings of the human mind. It's quite a mystery when a person who has it all: career, family, money, love, - takes his own life (recent case in my country), and leaves family and all around him utterly devastated and grieving. We need some more insight into that super computer - the brain- to be able to prevent, perhaps, this kind of tragedy.
Happy 2019!
