Based on prior knowledge, blood glucose levels can be used to determine whether a person is a senior or non-senior. However, the specific ranges for these age groups may vary depending on the context. Typically, a fasting blood glucose level of less than 100 mg/dL is considered normal for a non-senior adult, while a level above 100 mg/dL may indicate prediabetes or diabetes. For seniors, the cutoff values may be slightly higher.

Here is a dictionary with possible LBXGLU values for each target class:

```json
{
	"Adult": [80.5, 90, 95.2, 97.8, 99.1],
	"Senior": [100.2, 105, 110.6, 120, 130.3]
}
```

Please note that these values are just examples and should be adjusted based on the specific criteria used to define the age groups in your context.
