Don't be such a cheapskate. Thats some of the worst bar tape condition I've seen in a while.
No wonder you have numb hands.
Go to your LBS and look for some quality, cushion bar tape. Add an underlayment layer of cushion tape or do what I do, use an old tire tube, split down the middle, as the underlayment of the top layer of quality bar tape.
downtube42 noted, don't ride with the bar directly in the center channel of your palm/wrist - that's where the unlar nerve and most of the important blood vessels are.
Position your hands on the hoods so the bar is on the meaty outside of the palm. Level the bars, the tilt up does nothing positive.
Bends your elbows when you ride, and the bend will help absorb shocks which come up thru the bars.
Do things which improve your core strength and flexibility - Not doing anything will guarantee quicker aging and that will impact, negatively, everything! Not just riding a bike.
If you ride 1x or 2x a week, you're butt will hurt on rides an hour or longer. Ride a bit more.
Ride On
