Do you think Joe Biden is getting a shot of a performance enhancement drug?

Sometimes Joe seems to be OK, but then suddenly drops the act and goes senile.  It tends to make one wonder if he is getting a shot of a performance enhancement drug that causes him to perk up a bit. And why he stays in his basement for several days, then comes out, gives a quick speech, and then runs back into his basement. May be it is a drug like what they have banned on race horses and home run hitters in baseball.  But there is no such ban for politicians, or musicians.  Do you know what drug they are giving Biden?  Do you think it would help if Biden carried a guitar and frizzled his hair?
