ELFOOL thank you for your replay. Well alzheimer was a random example, i am sure that there are few orher disesases that still the person can communicate, or try it at the early state of alzheimer.

I got also an another idea but i guess this have to be tested from scientists into a special area like hospital. In order to explore more the dmt world, what if a stady and continuous dose of dmt always will flow into the volunteer's vein so he could stay into that world for more like 30+ minutes or more, there would be no restrictions.
