new kernels & rebooting

[Paul Cartwright]

Is it me, or does every other update lately seem to include a new
kernel.. I thought linux was meant to stay up & running. I seem to be
rebooting weekly now, just for a new kernel.  Now on:
uname -a
Linux pauls-server 3.15.6-200.fc20.x86_64 #1 SMP Fri Jul 18 02:36:27 UTC
2014 x86_64 x86_64 x86_64 GNU/Linux

is there some command I don't know about that will let you swap to the
latest kernel without rebooting???
the 3 latest kernels:
-rwxr-xr-x. 1 root root  5538536 Jul  7 10:32 vmlinuz-3.15.4-200.fc20.x86_64
-rwxr-xr-x. 1 root root  5538920 Jul 14 11:49 vmlinuz-3.15.5-200.fc20.x86_64
-rwxr-xr-x. 1 root root  5539144 Jul 17 22:49 vmlinuz-3.15.6-200.fc20.x86_64

in less than 10 days..
