how can i adjust bitcoin memory use age, i don't want more than 5 days worth of blockchain data.

If i'm understanding your question correctly, what you're looking for is pruning?

There's several guides online which show you exactly how to do this.

See https://bitcoin.stackexchange.com/questions/37496/how-can-i-run-bitcoind-in-pruning-mode

-prune= Reduce storage requirements by enabling pruning (deleting) of old blocks. This allows the pruneblockchain RPC to be called to delete specific blocks, and enables automatic pruning of old blocks if a target size in MiB is provided. This mode is incompatible with -txindex and -rescan. Warning: Reverting this setting requires re-downloading the entire blockchain. (default: 0 = disable pruning blocks, 1 = allow manual pruning via RPC, 550 = automatically prune block files to stay under the specified target size in MiB)

Or alternatively follow something like https://coinguides.org/bitcoin-blockchain-pruning/

Do note that you still will have to download/verify the entire chain (140+ GB of data)

The blockchain size 5/6 days ago was roughly 184.487 MB, vs 185.128mb now. I guess you should be able to calculate rather easily how much MB you'll need to allocate to save only the last 5 days.

Code:

185.128 - 184.487 =~ 641 MB
