Not one expect those who enjoy making love will agree with you.
It was joke.
Yes indeed this is this overall grand reality of happiness for every species. There are good times and there are bad times but overall Life remains good.And thats why they are alive.
Some say it is a complete nonsense to search for happiness outside as it is the function of your internal emotions which can be generated using internal belief.Think positive they say but how much they follow who knows.
