Additional Alzheimers' Test ... Thx Marge R!

Here's another trick of Doctor Dementia to test your skills... Can you meet this challenge? We've seen this with the letters out of order, but this is the first time we've seen it with numbers. Good example of a Brain Study: If you can read this OUT LOUD you have a strong mind. And better than that: Alzheimer's is a long long, way down the road before it ever gets anywhere near you. 7H15 M3554G3 53RV35 7O PR0V3 H0W 0UR M1ND5 C4N D0 4M4Z1NG 7H1NG5! 1MPR3551V3 7H1NG5! 1N 7H3 B3G1NN1NG 17 WA5 H4RD BU7 N0W, 0N 7H15 LIN3 Y0UR M1ND 1S R34D1NG 17 4U70M471C4LLY W17H0U7 3V3N 7H1NK1NG 4B0U7 17, B3 PROUD! 0NLY C3R741N P30PL3 C4N R3AD 7H15!

Only great minds can read this. This is weird, but interesting! If you can raed this, you have a sgtrane mnid, too. Can you raed this? Olny 55 people out of 100 can. I cdnuolt blveiee that I cluod aulaclty uesdnatnrd what I was rdanieg. The phaonmneal pweor of the hmuan mnid, aoccdrnig to a rscheearch at Cmabrigde Uinervtisy, it dseno't mtaetr in what oerdr the ltteres in a word are, the olny iproamtnt tihng is that the frsit and last ltteer be in the rghit pclae. The rset can be a taotl mses and you can still raed it whotuit a pboerlm. This is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the word as a wlohe. Azanmig huh? Yaeh and I awlyas tghuhot slpeling was ipmorantt! If you can raed this forwrad it. FORWARD ONLY IF YOU CAN READ IT..
