I've thought of that already. At the moment I don't own a saxophone, and I don't fancy practising 8 hours a day. Like I said, my body can't handle the horn. I have back problems, and I don't fancy having to work up chops. The reality is I will never sound like is did in my 20s. My face will never have the stamina. It's like being an athlete past your prime. Every day my body is deteriorating, and it would take longer and longer to heal from difficult long days of practise.
It's time to switch instruments. I'm interested in composing music for my YouTube videos, not practising saxophone all day. Again I've come to this decision after 15 years of thinking about out it.
Also for the cost of a new saxophone $5,000+, I could build a monster synth. Or build a modest synth, and buy more camera gear for my YouTube channel.
