Great book. But his recommendations are hard to follow.

40 minutes of zone 2 cardio at least 4 times a week plus zone 5 training once a week plus a strength training regimen plus mobility work.

I exercise about an hour 5-6 days a week and that isn’t enough to cover this regimen.

His recommendations make sense given that his most important indicator for longevity is exercise. But it’s a lot of time per day. Two hours some days if you really follow it.
