For example, here I am looking at a 64 GB (physical) machine which was booted about 30 minutes ago, and which is running disk-heavy workloads (installing VMs). Since I have started writing this email (2 minutes?), the amount of free memory has already gone down from 37 GB to 33 GB. I expect that by the time I have finished running the workload, in two hours, it will not have any free memory.
