Any long-term disadvantage to re-writing a variable?

Perhaps I'm overly complicating things, but you know how if you re-write an SSD (solid state computer hard drive) over and over you can eventually get bad (unrecoverable) sectors? (albeit it can take a long time to cause such a failure)

Is the same true with the Atmel chips on the Arduino board? If I'm re-writing a variable's value over and over (as part of the loop) am I causing something to wear out?

Why am I asking ... because in order to weed out erroneous sensor values I am checking a sensor value 4 times (4 passes of the loop), if it's within range all 4 times then it must be valid/true. If there's been more than 6 passes of the loop I'm resetting it to 0 to prevent an overflow. Either way, that's allot of repetitive "writes" to the variable - is this a problem?

There is no problem with "overwriting" a normal variable over and over again.
It would be different if the variable were in flash memory or EEPROM (but yours aren't, and you'd know it if they were, because they would be more difficult to write!)

I appreciate your insight/good news - thank you!
