Question about investing (Patreon)

Dear Patrons, I've used a 'quiet' keyboard for years now. But I agree with some viewers, it's not that quiet... They hear my typing over my heartbeat and it can be annoying.Do you think I should invest in an even quieter keyboard? Our just do silent heartbeat videos and not interact in the chat, just with thumbs up and down? (Which can be very confusing because of a little delay in chat and video etc.)Of course, other suggestions are very welcome.
