Note: There are only six different sorts of biological age in this dataset, which get reused for every sample for which they apply. While we could use the “drop duplicates” function to assign a unique system_id numbers to each of these, Roger feels this is not needed, as this is a descriptive field, and future datasets may have more variety in what they report for biological age.

decide if you want to change this to a combo of tbl_abundance_modifications and # tbl_modification_types as per Tom's suggestion of 2026-02-19
