Are you planning to combine it with other info? Your smartwatch already knows how long you've slept, getting that info directly to your database seems more efficient and less error prone. The same goes for the amount of money you've spend, if your bank allows you to export that info it'll save you a step. Your bank doesn't know what you've bought, only the total cost, time and shop, but if you scan and upload your receipts and use ocr you'll have a detailed record of that too.

And you could also keep track of your location, so you know where you had a conversation or at what gas station you spend 250,000
