As a former rock climber, I will make the most important observation:
There are no old free-climbers.
Yeah, is this young man still alive?
Back in the day I owned a climbing school/guide service and was spending around 150 days a year on the rock. I free climbed a bit, mostly 5.6-5.8 and all under 100 feet.
Looking back on that time makes me realize that although freeing a wall is the ultimate expression of the sport, only a precious few should attempt the things that Hollold does... and even then, for a very short window of time.
