Talking about solar activity cycles.
A Black sportsmen jumped at 8 m 90 cm in 1968.
This result was half a metre longer than previous record,
and was beaten just in 1991, also by a Black sportsman.
But still, this 1968 record is the third in history.
Not only wars and revolutions, vegetable world grows stronger in these years,
much higher crop, much better results.
Music of 1968-71 is not third in history, it's best in history.
The 1968-71 solar peak was the strongest in many years, not beaten since.
1990-91 was also strong, but not as strong as 1968.
That's why you should listen to 60-s-70-s music - it's much better than today's music.
Maybe you think the progress, 'we're much better now than our fathers and grandfathers',
but the fact stays the fact - music of the 60-s better than music of today.
